Abstract
The article presents the results of a study of photo detection in barrier modulation of the Au-CdP2 structures. Results of a study of the spectral and frequency characteristics of the photodiode with Schottky barrier are provided. The spectral and frequency characteristics of the FD are studied. Photodiode (PD) Schottky-barrier based on structure of Au-CdP2 are maded. The effect of barrier modulation under illumination of the structure are used. The layout of the receiving optical module are designed. Prospects of device using for fiber-optic communications systems are shown. A physical equivalent circuit of a photodiode are proposed. A combination of photodiode and electrical amplifier (model receiving optical module) are considered. The aim of the research, the results of which are presented in this work is to increase the sensitivity of photo-detectors for receiving information in optical communication systems under low light flows based on the use of new photosensitive materials and upgrading appliances. A substantial increase of photosensitivity is implemented through the use of the Schottky photodiode when a certain doping profile of a semiconductor substrate are creating.
