Description
Technical field
The invention belongs to Nanosemiconductor Device technical fields, more particularly to one kind being based on gold-cuprous oxide (Au-
Cu2O) the phasmon FET and preparation method thereof of nano wire reticular structure.
Background technology
Cuprous oxide is typical p-type semiconductor material, and direct band gap width is about 2.17eV, it is seen that the absorption model of light
It encloses relatively extensively, and it is about 100cm to have good hole mobility at room temperature2/ (V.s), is widely used photocatalysis,
Photovoltaic, the fields such as optical detection.But the light absorption length of cuprous oxide is about 10 μm, is far longer than its minority carrier
Diffusion length, so cuprous oxide is better than planar structure using nano thread structure.
Gold nano grain chemical property is relatively stablized, and in visible light region hypersorption, can be formed etc. on surface from swashing under illumination
Member has Surface enhanced Raman scattering, biocompatibility etc..
Metal can absorb the light of all wave bands, and semiconductor can only absorb the light that energy is more than its energy gap.Gold-oxygen
Change the performance that cuprous nanostructure is not only provided simultaneously with metal nanoparticle and nanometer semiconductor structure, semiconductor can also be made up
Characteristic in photoelectricity.Metal-semiconductor nanostructure is excited by illumination, metal surface phasmon, generates thermoelectricity
Son.When thermoelectron at metal and interface has sufficiently large energy, metal can be crossed and be in direct contact shape with semiconductor
At Schottky barrier, in the conduction band for reaching semiconductor.This may result in the photoelectric current enhancing of metal-semiconductor device.Metal-
Direct electric charge transfer between semiconductor improves the energy transfer efficiency from metal to semiconductor.Currently, field effect on the market
It is traditional technotron and Metal-oxide-semicondutor field-effect tube that should manage all, but utilize metal-semiconductor etc.
The field-effect tube device manufactured from excimer thermoelectron transfer has not been reported.
Invention content
It is a kind of based on gold-cuprous oxide (Au-Cu the purpose of the present invention is providing regarding to the issue above2O) nano wire is netted
Phasmon FET of structure and preparation method thereof.Metal-semiconductor nano composite structure field-effect tube is directly electric using thermoelectron
Lotus transfer increases the characteristic of semiconductor light electric current so that it is sensitiveer than traditional field-effect tube in terms of optical detection, visits
It is also wider to survey range, preparation method is simple, and technological parameter is controllable, and repeatability is high.
The invention mainly includes steps：Make nano cuprous oxide wire；Surfactant and weak reductant are dissolved
Into distilled water, it is heated to 85-95 DEG C, and keep constant temperature, then nano cuprous oxide wire is poured into solution, stirs, mixed
Close solution；The pH value of adjusting tetra chlorauric acid solution is molten by the tetra chlorauric acid of 0.25-1ml after solution stirring to be mixed to alkalescent
Liquid is slowly added in mixed solution, forms Au-Cu2O nano composite structures；By the Au-Cu2O nano composite structures be dissolved in water with
In the small solvent mixed liquor of surface tension, Au-Cu is obtained2O nano composite structure solution；Using liquid technology by Au-Cu2O nanometers
Composite construction solution is uniformly taped against on pectination backgate FET substrates, forms nano wire reticular structure, low temperature naturally dry；It is rare
Under gas, low temperature thermal annealing, it is ensured that nano composite structure and the gold thread Ohmic contact on substrate are produced with the Au-
Cu2The pectination backgate FET of O nano wire reticular structures.Production method of the present invention have it is simple, quickly, it is of low cost the features such as, than
Traditional FET is sensitiveer, and investigative range is also wider.
Technical scheme of the present invention is specifically：One kind being based on gold-nano cuprous oxide wire reticular structure phasmon FET systems
Preparation Method includes the following steps：
Make nano cuprous oxide wire：The Salicylaldoxime of 0.15g is completely dissolved in the distilled water of 40ml, then takes 69 μ l
Pyrroles be completely dissolved in the distilled water of 10ml, after then both solution are mixed evenly, pour into 50ml autoclaves,
180 DEG C of heating 10h, then cool to room temperature, clean impurity, take out the nano cuprous oxide wire of yellow green；
Surfactant and weak reductant are added in the distilled water of 10ml, stirs to being completely dissolved, is subsequently heated to
85-95 DEG C, and constant temperature is kept, then nano cuprous oxide wire is poured into solution, and it is filled with rare gas, such as argon gas,
It keeps stirring, obtains mixed solution；
The pH value of tetra chlorauric acid solution is adjusted to alkalescent, after solution to be mixed stirs ten minutes, by the four of 0.25-1ml
Chlorauric acid solution drop is slowly added in heating water bath and the mixed solution that keeps stirring, after 1-2.5h, take out using liquid phase from
Heart isolation technics detaches nano composite structure with reaction solution, obtains pure Au-Cu2O nano composite structures；
By the Au-Cu2O nano composite structures are dissolved in water with the small solvent mixed liquor of surface tension, obtain Au-Cu2O
Nano composite structure solution；
Using liquid technology by Au-Cu2O nano composite structures solution is uniformly taped against pectination back gate field-effect transistor substrate
On, nano wire reticular structure is formed, low temperature naturally dry is repeated several times；Under rare gas, low temperature thermal annealing, it is ensured that nanometer is multiple
Structure and the gold thread Ohmic contact on substrate are closed, is produced with the Au-Cu2The pectination backgate of O nano wire reticular structures
FET。
In said program, the surfactant is the k values of the polyvinylpyrrolidone PVP, PVP of 0.0106-0.0318g
It is 30000, the weak reductant is the ascorbic acid of 0.033-0.1g.Surfactant makes nano cuprous oxide wire more hold
Easily growth gold particle, after there is PVP good dissolubility to be not only dissolved in water but also can be dissolved in alcohols, easy to clean, and PVP is dissolved in water
It forms colloid and protects cuprous oxide crystal face.Cuprous oxide can be prevented to be reduced using weak reductant.
