Emission properties of an array of silicon nanocones

Abstract

In this paper we investigate the emission properties of an array of silicon nanocones containing cobalt nanoparticles at their vertices. Nanocones are formed on a silicon substrate by deposition a cobalt film, processing it to obtain an array of nanoparticles with a diameter of 20-30 nm and subsequent etching of silicon. Nanocones of silicon are separated from the conductive substrate by a layer of silicon oxynitride with the thickness of 8 nm. The results of modeling the current transfer in Si(Sb)/SiOxNy/Co nanocones and an estimation of their emission properties are presented.
