Research of the solar-blind and visible-blind photodetectors, based on the AlGaN solid solutions

Abstract

The paper is devoted to the development and study of solar-blind and visible-blind photodetectors. We report on the spectral characteristics of the ultraviolet photodetectors based on Shottky barrier to the epitaxial layers of the n-AlxGa1-xN solid solutions. The use of Schottky barrier photodiodes is advantageous since it does not require the growth of additional epitaxial layer of p-type conductivity.
