Paper Abstract

Properties of n+-on-p HgCdTe photodiode with graded p-P heterojunction at temperature 77 K are analysed numerically by solving three-dimensional diffusion equation in cylindrical geometry. Dependences of photodiode's parameters from composition difference Δx and position of p-n junction in relation to heterojunction are presented. Elimination of lateral collection of diffusion current with increasing of Δx is shown.
