Abstract

A numerical technique has been used to solve the carrier transport equations for Hg_1-xCd_xTe and InAs_1-xSb_x photodiode operating near room temperature. The model calculates the spatial distribution of the electric field, the electron hole concentrations and the generation-recombination mechanisms. Also the effect of doping profiles on the photodiode parameters (R₀A product, detectivity) is analyzed. The R₀A product is controlled by a diffusion limited mechanism. In the case of HgCdTe photodiodes, only two processes of generation and recombination are important: Auger 1 and Auger 7; whereas in InAsSb photodiodes also the Auger S process has an essential significance. It is proved that Hg_1-xCd_xTe and InAs_{1- x}Sb_x photodiodes of optimum construction have similar detection parameters. This fact together with some advantages of InAsSb in comparison with HgCdTe indicates that InAsSb ia a potential competitor to HgCdTe as material for intrinsic detectors in the 3-5 micrometers and 8-12 micrometers spectral range.
