Abstract

"Nueva fuente de emisión electrónica constituida por nanoestructuras tubulares de nitruro de boro y su fabricación". En el diseño de la mayoría de los cátodos comerciales se busca obtener la mayor emisión de electrones al menor coste, es decir, operando a temperatura ambiente y a pequeños voltajes aplicados. Sin embargo, en la actualidad, para obtener emisiones electrónicas adecuadas por unidad de área típicamente se necesitan altas temperaturas (entre 1000 y a 2600 grados Kelvin) y/o un elevado campo eléctrico aplicado (10{sup,3}-10{sup,4} Voltios/micrómetro. Un micrómetro, {mi}m, es igual a 10{sup-6} metros). Con la siguiente invención se resuelven estos problemas mediante la caracterización de las estructuras geométricas óptimas de los nanotubos de nitruro de boro (BN) y el diseño de una fuente de emisión de electrones extremadamente ligera formada por estas estructuras tubulares de BN que funciona a pequeños campos eléctricos aplicados."New source of electronic emission constituted by tubular nanostructures of boron nitride and its manufacture". The design of most commercial cathodes seeks to obtain the highest emission of electrons at the lowest cost, that is, operating at room temperature and at small applied voltages. However, at present, high temperatures (between 1000 and 2600 degrees Kelvin) and / or a high applied electric field (10 {sup, 3} -10 {sup, 4) are typically required to obtain adequate electronic emissions per unit area. } Volts / micrometer One micrometer, {mi} m, is equal to 10 {sup-6} meters). With the following invention, these problems are solved by characterizing the optimal geometric structures of the boron nitride nanotubes (BN) and designing an extremely light electron emission source formed by these tubular BN structures that operate in small fields Applied electrical
