Abstract

The present application relates to the field of nanotechnology, and in particular to a method for manufacturing a nanostructure. The method comprises: according to a pre-set first pattern template, writing charges on a substrate having low surface energy, so that the substrate is chemically modified in a region where the charges are written, so as to form a first nanopattern; and introducing first nanoparticles in a region where the first nanopattern is located, so as to form a first nanostructure. The substrate itself has low surface energy, and by writing charges, the first nanopattern enables the surface of the substrate to be chemically modified. Therefore, the first nanopattern having high surface energy can be formed on the substrate. Therefore, the first nanoparticles can be precisely adsorbed in the region, where the first nanopattern is located, under the action of high surface energy, while the region, other than the first nanopattern, on the substrate has low surface energy and thus cannot adsorb the first nanoparticles, and the problem of non-specific adsorption in the prior is prevented from occurring, thereby allowing the formed first nanostructure to be cleaner.

为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。In order to make the purpose, technical solutions, and advantages of the present application clearer, the following further describes the embodiments of the present application in detail with reference to the accompanying drawings.
图1示例性示出了本申请实施例提供的一种纳米结构的制造方法所对应的流程示意图。如图1所示,具体包括如下步骤:FIG. 1 exemplarily shows a schematic flow chart corresponding to a method for manufacturing a nanostructure provided by an embodiment of the present application. As shown in Figure 1, it specifically includes the following steps:
步骤101,提供第一图案模板。Step 101: Provide a first pattern template.
步骤102,根据待形成的纳米图案,在具有低表面能的衬底上写入电荷,以使所述衬底在写入电荷的区域产生化学改性,形成具有高表面能的第一纳米图案。Step 102, according to the nano pattern to be formed, write charges on the substrate with low surface energy, so that the substrate is chemically modified in the area where the charges are written to form a first nano pattern with high surface energy .
步骤103,在具有高表面能的第一纳米图案所在的区域引入第一纳米颗粒,形成第一纳米结构。Step 103: Introduce the first nano-particles into the area where the first nano-pattern with high surface energy is located to form the first nano-structure.
本申请实施例中,由于衬底本身是具有低表面能的,而第一纳米图案是采用写入电荷的方式使得衬底表面的化学键断裂,产生化学改性,从而能够在衬底上形成具有高表面能的第一纳米图案。因此,在引入第一纳米颗粒时,第一纳米颗粒在高表面能的作用下,可以精确吸附在第一纳米图案所在的区域,而衬底上除第一纳米图案以外的区域的表面能较低,不会吸附第一纳米颗粒,能够提高纳米结构的精度,也不会产 生现有技术中的非特异性吸附的问题,与现有的纳米结构的制造方法相比,采用本申请实施例提供的方法制成的纳米结构更加干净。In the embodiments of the present application, since the substrate itself has low surface energy, the first nanopattern adopts the method of writing charges to break the chemical bonds on the surface of the substrate, resulting in chemical modification, so that it can be formed on the substrate. The first nano pattern with high surface energy. Therefore, when the first nanoparticle is introduced, the first nanoparticle can be accurately adsorbed on the area where the first nanopattern is located under the action of high surface energy, and the surface energy of the area on the substrate except the first nanopattern is relatively high. It is low, does not adsorb the first nanoparticles, can improve the precision of the nanostructure, and does not cause the problem of non-specific adsorption in the prior art. Compared with the existing manufacturing method of the nanostructure, the embodiments of the present application are used. The nanostructure made by the method is cleaner.
在执行步骤101之后,可以先制备具有低表面能的衬底。具体来说,可以在导电衬底上涂覆一层具有低表面能的驻极体薄层,从而组成具有低表面能的衬底。After performing step 101, a substrate with low surface energy may be prepared first. Specifically, a thin layer of electret with low surface energy can be coated on the conductive substrate to form a substrate with low surface energy.
其中,驻极体可以指的是一种电介质材料,它具备几乎永久的电荷或极化的保存能力,可以在其内部和外部产生电场。比如,铁电材料,聚合物材料等都是驻极体。Among them, electret can refer to a kind of dielectric material, it has almost permanent electric charge or polarization preservation ability, can produce electric field inside and outside. For example, ferroelectric materials, polymer materials, etc. are all electrets.
进一步地,采用上述方法制成的衬底的结构如图2所示,为本申请实施例提供的一种具有低表面能的衬底的结构示意图。其中,在导电衬底的表面涂覆有一层驻极体薄层。Further, the structure of the substrate manufactured by the above method is shown in FIG. 2, which is a schematic structural diagram of a substrate with low surface energy provided by an embodiment of the application. Wherein, a thin layer of electret is coated on the surface of the conductive substrate.
更进一步地,驻极体薄层可以为多种类型的驻极体材料,从而可以制备多种类型的具有低表面能的衬底。例如,驻极体薄层可以为含氟的驻极体化合物;或者,也可以为含氟的驻极体聚合物;或者,也可以为含氯的驻极体化合物;或者,还可以含氯的驻极体聚合物。Furthermore, the electret thin layer can be multiple types of electret materials, so that multiple types of substrates with low surface energy can be prepared. For example, the electret thin layer may be a fluorine-containing electret compound; or, it may be a fluorine-containing electret polymer; or, it may also be a chlorine-containing electret compound; or, it may also contain chlorine. Of electret polymers.
步骤101中,第一图案模板可以包括具有低表面能的衬底和待形成的纳米图案。In step 101, the first pattern template may include a substrate with low surface energy and a nano pattern to be formed.
其中,表面能可以是指恒温、恒压、恒组成的情况下,可逆地增加物系表面积须对物质所做的非体积功;换言之,表面能可以是表面粒子相对于内部粒子所多出的能量。Among them, the surface energy can refer to the non-volume work that must be done to the substance to reversibly increase the surface area of the material system under the condition of constant temperature, constant pressure, and constant composition; in other words, the surface energy can be the excess of surface particles relative to internal particles energy.
步骤102中,在衬底上写入电荷,从而形成第一纳米图案的方法有多种。一个示例中,如图3a所示,为本申请实施例提供的一种形成纳米图案的示意图之一。具体来说,可以根据待形成的纳米图案,采用导电的纳米探针在具有低表面能的衬底上写入电荷,从而形成具有高表面能的第一纳米图案。In step 102, there are many methods for writing charges on the substrate to form the first nanopattern. In an example, as shown in FIG. 3a, it is one of the schematic diagrams of forming a nano pattern according to an embodiment of this application. Specifically, according to the nano pattern to be formed, a conductive nano probe may be used to write charges on the substrate with low surface energy, thereby forming the first nano pattern with high surface energy.
其中,导电的纳米探针可以是导电原子力显微镜探针。Among them, the conductive nanoprobe may be a conductive atomic force microscope probe.
又一个示例中,如图3b所示,为本申请实施例提供的一种形成纳米图案的示意图之二。具体来说,可以根据待形成的纳米图案,采用导电的纳米***对与具有低表面能的衬底接触的区域施加电压,以写入电荷,从而形成具有高表面能的第一纳米图案。In another example, as shown in FIG. 3b, it is the second schematic diagram of forming a nano pattern according to an embodiment of the present application. Specifically, according to the nano pattern to be formed, a conductive nano stamp may be used to apply a voltage to the area contacting the substrate with low surface energy to write charges, thereby forming the first nano pattern with high surface energy.
其中,导电的纳米***可以为刻有预设的第一图案模板的金属或半导体模板,或者可以为刻有预设的第一图案模板且表面镀有导电金属层的氧化物模板,或者可以为刻有预设的第一图案模板且表面镀有导电金属层的聚合物模板,具体不做限定。Wherein, the conductive nano-seal may be a metal or semiconductor template engraved with a preset first pattern template, or may be an oxide template engraved with a preset first pattern template and coated with a conductive metal layer on the surface, or may be The polymer template engraved with the preset first pattern template and coated with a conductive metal layer is not specifically limited.
又一个示例中,如图3c示,为本申请实施例提供的一种形成纳米图案的示意图之三。具体来说,可以根据待形成的纳米图案,在具有低表面能的衬底上施加电子束或离子束,以写入电荷,从而形成具有高表面能的第一纳米图案。In another example, as shown in FIG. 3c, it is the third schematic diagram of forming a nano pattern according to an embodiment of the present application. Specifically, according to the nano pattern to be formed, an electron beam or an ion beam may be applied to a substrate with a low surface energy to write charges, thereby forming a first nano pattern with a high surface energy.
在其它可能的示例中,也可以采用其它方法在衬底上写入电荷,具体不做限定。In other possible examples, other methods may also be used to write charges on the substrate, which are not specifically limited.
需要说明的是,无论是上述哪种示例给出的写入电荷的方法,所形成的第一纳米图案可以直接由开尔文探针技术(Kalvin Probe Force Microscope,KPFM)测量。在写入电荷的过程中,电子或离子会导致衬底出现表面改性的现象,以衬底表面装饰有含氟(或含氯)化合物为例,电子或离子会导致含氟(或含氯)化合物的改性,从而能够提高所形成的第一纳米图案所在的区域的表面能,进而可以使得该第一纳米图案所在的区域易于吸附第一纳米颗粒。进而,由于高表面能对应高摩擦力(即切向力),第一纳米图案可直接由原子力显微镜的切向力模式进行表征。It should be noted that, regardless of the method of writing charge given in the above example, the first nanopattern formed can be directly measured by the Kelvin Probe Force Microscope (KPFM). In the process of writing charges, electrons or ions will cause surface modification of the substrate. Taking the surface of the substrate decorated with fluorine (or chlorine) compounds as an example, electrons or ions will cause fluorine (or chlorine) ) The modification of the compound can increase the surface energy of the area where the first nanopattern is formed, thereby making it easy for the area where the first nanopattern is to adsorb the first nanoparticles. Furthermore, since high surface energy corresponds to high friction (ie, tangential force), the first nanopattern can be directly characterized by the tangential force mode of the atomic force microscope.
相比于传统的纳米图案的制备方法,本申请实施例中可以直接写入电荷制备纳米图案,无需引入新的材料(比如现有的基于表面化学改性的方法制备的纳米图案,需要引入化学材料),本申请的制备方法更加简便快捷。Compared with the traditional method for preparing nano-patterns, in the examples of this application, charges can be directly written to prepare nano-patterns, without introducing new materials (such as the existing nano-patterns prepared based on surface chemical modification methods, which require the introduction of chemical Material), the preparation method of this application is simpler and faster.
步骤103中,第一纳米颗粒可以采用多种方法引入到具有高表面能的第一纳米图案所在的区域,例如,可以采用旋涂法引入纳米颗粒,或者也可以采用涂覆法引入纳米颗粒,或者也可以采用提拉法引入纳米颗粒,或者还可以采用气相喷涂发引入纳米颗粒,具体不做限定。In step 103, the first nano-particles can be introduced into the area where the first nano-pattern with high surface energy is located by various methods. For example, the spin-coating method can be used to introduce the nano-particles, or the coating method can also be used to introduce the nano-particles. Alternatively, the pulling method may be used to introduce the nanoparticles, or the vapor spraying method may also be used to introduce the nanoparticles, which is not specifically limited.
以旋涂法为例,如图4a所示,为本申请实施例提供的采用旋涂法引入纳米颗粒的示意图。具体来说,可以将由第一纳米颗粒组成的溶液滴在具有高表面能的第一纳米图案所在的区域,同时按照预设的旋转速度以衬底的中心轴线(图4a中示出的L轴)为旋转轴转动衬底,从而形成第一纳米结构。其中,衬底的中心轴线为垂直于衬底所在的平面且穿过衬底的中心点(图4a中示出的O点)的轴线。Taking the spin coating method as an example, as shown in FIG. 4a, a schematic diagram of introducing nanoparticles by the spin coating method provided in this embodiment of the application. Specifically, the solution composed of the first nano-particles can be dropped on the area where the first nano-pattern with high surface energy is located, and at the same time at a preset rotation speed at the center axis of the substrate (the L axis shown in Figure 4a) ) Is the rotation axis to rotate the substrate to form the first nanostructure. The central axis of the substrate is an axis perpendicular to the plane where the substrate is located and passing through the central point of the substrate (point O shown in FIG. 4a).
进一步地,预设的旋转速度可以设置在1000转/分钟至10000转/每分钟的范围内,本领域技术人员可以根据实际需要来确定旋转速度的取值,具体不做限定。Further, the preset rotation speed may be set in the range of 1000 revolutions/minute to 10000 revolutions/minute, and those skilled in the art can determine the value of the rotation speed according to actual needs, which is not specifically limited.
以涂覆法为例,如图4b所示,为本申请实施例提供的采用涂覆法引入纳米颗粒的示意图。具体来说,可以使用刷子将由第一纳米颗粒组成的溶液刷在具有高表面能的第一纳米图案所在的区域,从而形成第一纳米结构。Taking the coating method as an example, as shown in FIG. 4b, a schematic diagram of introducing nanoparticles by the coating method provided in this embodiment of the application. Specifically, a brush may be used to brush the solution composed of the first nanoparticles on the area where the first nanopattern with high surface energy is located, thereby forming the first nanostructure.
以提拉法为例,如图4c所示,为本申请实施例提供的采用提拉法引入纳米颗粒的示意图。具体来说,可以将衬底浸入由第一纳米颗粒组成的溶液中,如此,第一纳米颗粒被吸附到具有高表面能的第一纳米图案所在的区域,从而形成第一纳米结构。Taking the pulling method as an example, as shown in FIG. 4c, a schematic diagram of introducing nanoparticles by the pulling method provided in this embodiment of the application. Specifically, the substrate may be immersed in a solution composed of first nanoparticles, so that the first nanoparticles are adsorbed to the region where the first nanopatterns with high surface energy are located, thereby forming the first nanostructure.
以气相喷涂法为例,如图4d所示,为本申请实施例提供的采用气相喷涂法引入纳米颗粒的示意图。具体来说,喷枪中存放有由第一纳米颗粒组成的气体,然后使用喷枪向具有高表面能的第一纳米图案所在的区域喷射该气体,从而形成第一纳米结构。Taking the vapor spraying method as an example, as shown in FIG. 4d, a schematic diagram of introducing nanoparticles by the vapor spraying method provided in this embodiment of the application. Specifically, a gas composed of first nanoparticles is stored in the spray gun, and then the spray gun is used to spray the gas to the region where the first nano pattern with high surface energy is located, thereby forming the first nanostructure.
需要说明的是,由于本申请实施例提供的纳米结构的制造方法不存在非特异性吸附的问题,因此,上述四种纳米颗粒的引入方法均可实现纳米颗粒在大面积纳米图案上均匀且快速的引入。本领域技术人员可以根据实际情况选择合适的纳米颗粒的引入方法,具体不做限定。It should be noted that, because the manufacturing method of nanostructures provided in the embodiments of the present application does not have the problem of non-specific adsorption, the above four methods of introducing nanoparticles can all achieve uniform and rapid nanoparticle patterning on a large area. Introduce. Those skilled in the art can choose a suitable method for introducing nanoparticles according to actual conditions, and the specific method is not limited.
进一步地,第一纳米颗粒被引入后,将自行在第一纳米图案所在区域进行组装,从而形成第一纳米结构。如图5所示,为本申请实施例中纳米颗粒组装的示意图。具体组装过程涉及到两个过程,过程一是第一纳米颗粒被静电诱导在第一纳米图案附近,并实现快速富集;过程二是富集在一起的纳米颗粒由于衬底在第一纳米图案所在的区域和除第一纳米图案以外的其它区域之间表面能存在差异,第一纳米颗粒将选择性的吸附于高表面能区域,即吸附于第一纳米图案所在的区域。Further, after the first nano-particles are introduced, they will assemble themselves in the area where the first nano-pattern is located, thereby forming the first nano-structure. As shown in FIG. 5, it is a schematic diagram of nanoparticle assembly in an embodiment of this application. The specific assembly process involves two processes. The first process is that the first nano-particles are electrostatically induced near the first nano-pattern to achieve rapid enrichment; the second is that the enriched nanoparticles are in the first nano-pattern due to the substrate. There is a difference in surface energy between the area where it is located and the area other than the first nanopattern. The first nanoparticle will selectively adsorb to the high surface energy area, that is, the area where the first nanopattern is located.
在具体的表面吸附过程中,第一纳米颗粒将选择性的吸附于高表面能区域是由于衬底的表面能的调制,由于第一纳米图案所在的区域被改性,有着更高的表面能,相对衬底上除第一纳米图案以外的区域(即未被改性的区域),第一纳米颗粒将有选择的吸附在被改性区域。In the specific surface adsorption process, the first nanoparticle will selectively adsorb to the high surface energy area due to the modulation of the surface energy of the substrate. Because the area where the first nano pattern is located is modified, it has a higher surface energy , The first nano-particles will be selectively adsorbed on the modified area on the area on the substrate other than the first nano-pattern (that is, the unmodified area).
并且,上述过程属于物理吸附,与现有的表面化学改性的方法相比,本申请实施 例提供的方法不依赖于特定的化学官能团间的非特异性性吸附,因此,该过程对纳米颗粒的表面也没有要求。这一点上与其它依赖于表面改性的方法有着本质不同。同时,由于未改性区域表面能低,不会吸附纳米颗粒,因此,本申请实施例提供的方法可以解决现有技术中的纳米结构存在非特异性吸附的问题。Moreover, the above process belongs to physical adsorption. Compared with the existing surface chemical modification method, the method provided in the examples of this application does not rely on the non-specific adsorption between specific chemical functional groups. Therefore, the process has a negative effect on nanoparticles. There is no requirement on the surface. This is fundamentally different from other methods that rely on surface modification. At the same time, since the surface energy of the unmodified area is low and the nanoparticles will not be adsorbed, the method provided in the embodiments of the present application can solve the problem of non-specific adsorption of nanostructures in the prior art.
在具体的静电诱导使得纳米颗粒富集过程中,如果衬底本身携带电荷,则纳米颗粒主要受到两种静电作用力,一种作用力是衬底所携带的电荷与纳米颗粒所携带的电荷之间的库伦力,另一种作用力是纳米颗粒在非均匀电场中受到的梯度力。如果衬底本身不携带电荷,则纳米颗粒主要受到梯度力的作用。In the specific electrostatic induction process of enriching nanoparticles, if the substrate itself carries charges, the nanoparticles are mainly subjected to two electrostatic forces. One force is the difference between the charge carried by the substrate and the charge carried by the nanoparticles. The other kind of force is the gradient force that nanoparticles receive in a non-uniform electric field. If the substrate itself does not carry charges, the nanoparticles are mainly subjected to gradient forces.
进一步地,在梯度力的作用下,第一纳米颗粒被推向第一纳米图案所在的区域,这一过程与纳米颗粒本身是否携带电荷无关。如此,采用本申请实施例提供的纳米结构的制造方法,无需考虑纳米颗粒的材料,适用范围较广。Further, under the action of the gradient force, the first nanoparticle is pushed to the area where the first nanopattern is located, and this process has nothing to do with whether the nanoparticle itself carries electric charge. In this way, the nanostructure manufacturing method provided in the embodiments of the present application does not need to consider the material of the nanoparticle, and the application range is wide.
需要说明的是,对于携带电荷的纳米颗粒,由于同种纳米颗粒(即纳米颗粒同携带正电荷,或同携带负电荷)相互排斥,故纳米颗粒可组装成单分散颗粒构成的纳米结构;对于不携带电荷的纳米颗粒,由于各纳米颗粒之间不存在静电排斥作用,故纳米颗粒可组装成密排的纳米结构,这就可以实现制造需要连续结构的应用(比如电极,波导等)。It should be noted that, for nanoparticles carrying charges, because nanoparticles of the same kind (that is, nanoparticles with the same positive charge or with the same negative charge) repel each other, the nanoparticles can be assembled into nanostructures composed of monodisperse particles; For the nanoparticles that do not carry electric charge, because there is no electrostatic repulsion between the nanoparticles, the nanoparticles can be assembled into close-packed nanostructures, which can realize the manufacture of applications that require continuous structures (such as electrodes, waveguides, etc.).
在执行步骤103之后,本申请实施例还提供一种复合纳米结构的制造方法,如图6所示,为本申请实施例提供的一种复合纳米结构的制造方法所对应的流程示意图,具体包括如下步骤:After step 103 is performed, an embodiment of the present application further provides a method for manufacturing a composite nanostructure. As shown in FIG. 6, a schematic flow diagram corresponding to the method for manufacturing a composite nanostructure provided by this embodiment of the present application specifically includes The following steps:
步骤601,采用定位***确定所述第一纳米结构的空间位置。Step 601: Use a positioning system to determine the spatial position of the first nanostructure.
其中,显微镜探针可以是导电的原子力显微镜探针。Among them, the microscope probe may be a conductive atomic force microscope probe.
步骤602,根据第一纳米结构之间的空间位置,调整二次形成的纳米图案的位置信息。Step 602: Adjust the position information of the secondly formed nano pattern according to the spatial position between the first nano structures.
其中,二次形成的纳米图案的位置信息可以包括二次形成的纳米图案的位置坐标、二次形成的纳米图案的图案方向和二次形成的纳米图案的图案尺寸中的至少一项。Wherein, the position information of the secondly formed nano pattern may include at least one of the position coordinates of the secondly formed nano pattern, the pattern direction of the secondly formed nano pattern, and the pattern size of the secondly formed nano pattern.
采用上述第一纳米结构之间的空间位置来调整第二图案模板,可以保证第二纳米结构与第一纳米结构之间的精确对准。Using the above-mentioned spatial position between the first nanostructures to adjust the second pattern template can ensure accurate alignment between the second nanostructures and the first nanostructures.
步骤603,根据调整后的二次形成的纳米图案的位置信息,在具有低表面能的衬底上写入电荷,以使所述衬底在写入电荷的区域产生化学改性,形成具有高表面能的第二纳米图案。Step 603, according to the adjusted position information of the secondly formed nano pattern, write charges on the substrate with low surface energy, so that the substrate is chemically modified in the area where the charges are written to form a high The second nanopattern of surface energy.
步骤604,在具有高表面能的第二纳米图案所在的区域引入第二纳米颗粒,以使所述衬底在写入电荷的区域产生化学改性,形成第二纳米结构。Step 604: Introduce second nanoparticles into the area where the second nanopattern with high surface energy is located, so that the substrate is chemically modified in the area where charges are written to form a second nanostructure.
其中,第二纳米结构的制造方法与上文所描述的第一纳米结构的制造方法类似,此处不再详细描述。The method for manufacturing the second nanostructure is similar to the method for manufacturing the first nanostructure described above, and will not be described in detail here.
步骤605,组装第一纳米结构和所述第二纳米结构,得到复合纳米结构。Step 605: Assemble the first nanostructure and the second nanostructure to obtain a composite nanostructure.
本申请实施例提供的复合纳米结构的制造方法,相比于现有技术中的纳米结构由于存在非特异性吸附的问题,在组装成复合纳米结构的过程中,非特异性吸附造成的缺陷将被累计放大,因此,现有的复合纳米结构精度较低。而本申请实施例中,第一 纳米结构在形成的过程中无非特异性吸附的问题,具有极高的特异性,适合多次组装纳米结构,从而形成复合纳米结构。进一步地,本申请实施例中,纳米图案的制备仅依靠电荷制备,无需对衬底形貌进行改变,也无需引入新的化学材料作为模板,从而适合多次组装纳米结构。Compared with the nanostructures in the prior art, the method for manufacturing the composite nanostructures provided by the embodiments of the present application has the problem of non-specific adsorption. In the process of assembling the composite nanostructures, the defects caused by non-specific adsorption will be accumulated Amplification, therefore, the existing composite nanostructures have lower precision. In the embodiment of the present application, the first nanostructure has no problem of non-specific adsorption during the formation process, has extremely high specificity, and is suitable for assembling the nanostructure multiple times to form a composite nanostructure. Further, in the embodiments of the present application, the preparation of the nano-patterns only relies on electric charge preparation, without changing the morphology of the substrate, and without introducing new chemical materials as templates, which is suitable for assembling nano-structures multiple times.
需要说明的是,图6示出的复合纳米结构的制造方法仅为一种示例,在其它可能的示例中,步骤601中也可以通过预先设计的标记物来来实现,具体可以使用光学显微镜(或电子显微镜、或扫描探针显微镜)精确确定标记的位置,并利用其对第二纳米图案的尺寸进行对准。It should be noted that the manufacturing method of the composite nanostructure shown in FIG. 6 is only an example. In other possible examples, step 601 can also be implemented by pre-designed markers, specifically, an optical microscope ( Or electron microscope, or scanning probe microscope) accurately determine the position of the mark, and use it to align the size of the second nano pattern.

Any one of the magnetic nanoparticles is not specifically limited.
第二纳米颗粒的材料可以与第一纳米颗粒相同,也可以不同。考虑到复合纳米结构中通常存在材料不同的纳米结构,基于此,第二纳米颗粒可以为原子、分子、离子、团簇、半导体量子点、金属纳米颗粒、绝缘体纳米颗粒、超顺磁纳米颗粒中除所述第一纳米颗粒以外的任意一项,具体不做限定。The material of the second nanoparticle can be the same as or different from the first nanoparticle. Considering that there are usually nanostructures with different materials in composite nanostructures, based on this, the second nanoparticle can be atoms, molecules, ions, clusters, semiconductor quantum dots, metal nanoparticles, insulator nanoparticles, and superparamagnetic nanoparticles. Any item other than the first nanoparticle is not specifically limited.
进一步地,纳米颗粒的材料可以是液相的,从而可以在液-固界面形成纳米结构,如图4a、图4b和图4c示出的示意图中,液态的纳米颗粒在固态的衬底上形成纳米结构;或者,纳米颗粒也可以是气相的,从而在气-固界面形成纳米结构,如图4d示出的示意图中,液态的纳米颗粒在固态的衬底上形成纳米结构。Further, the material of the nanoparticle can be liquid, so that nanostructures can be formed at the liquid-solid interface.

In the schematic diagram shown in FIG. 4d, liquid nanoparticles form nanostructures on a solid substrate.
更进一步地,采用本申请提供的方法制造的纳米结构,该纳米结构的尺寸由纳米颗粒的尺寸和纳米图案的尺寸决定的,而纳米颗粒的尺寸和纳米图案的尺寸均可达到10纳米以下,甚至到1纳米尺度,因此本申请中的制造方法可以高速度、高精度、低成本地实现更高精度的纳米结构的制造。Furthermore, the nanostructure manufactured by the method provided in this application, the size of the nanostructure is determined by the size of the nanoparticle and the size of the nanopattern, and the size of the nanoparticle and the size of the nanopattern can reach 10 nanometers or less, Even to the scale of 1 nanometer, the manufacturing method in this application can realize the manufacturing of higher-precision nanostructures at high speed, high precision, and low cost.
本申请实施例中,所形成的纳米结构的尺寸可通过调节制造过程中的参数(该参考可以包括纳米图案的尺寸、写入电荷所需的电压、纳米颗粒组成的溶液的浓度以及引入纳米颗粒的方式和参数)来调节。举个例子,本申请实施例中,可以固定纳米图案的尺寸、纳米颗粒组成的溶液的浓度以及引入纳米颗粒的方式和参数,但改变写入电荷所需的电压,可以实现对纳米结构的尺寸的精确调节。In the embodiments of the present application, the size of the formed nanostructure can be adjusted by adjusting the parameters in the manufacturing process (the reference may include the size of the nanopattern, the voltage required for writing charges, the concentration of the solution composed of nanoparticles, and the introduction of nanoparticles. Method and parameters) to adjust. For example, in the embodiment of the present application, the size of the nano pattern, the concentration of the solution composed of the nanoparticles, and the method and parameters of introducing the nanoparticles can be fixed, but the voltage required to write the charge can be changed to achieve the size of the nano structure.
