Abstract :
Functionally graded materials are widely applied for mechanical applications. Nowadays they become more and more attractive for electronic and optoelectronic devices fabrication. This is caused by their unique properties. FGM are potential candidates for high sensitive photonic devices which could operate in a wide spectral range (also for voltage tunable photodetectors). In this paper the analysis of several photodetectors constructions fabricated in FGM were presented. The influence of AIII-BV (N) grading layers composition and configuration of the detector on its optical and electrical properties was discussed. Also the comparison between conventional non-graded and graded devices was shown. All simulations presented in the work were performed by the specialized software designed for modeling of AIII-BV (N) graded structures. The software allows us to calculate both the parameters of FMG structure and device characteristics
