Abstract

Decreasing dimensions along with increasing number of elements in imaging photodiode arrays result in degradation of spatial resolution and sensitivity due to lateral transport. This effect is modelled using a novel three-dimensional (3-D) analytical solution of the continuity equation. The model enables the full 3-D analysis of lateral transport as manifested in excess carrier distribution photocurrent, self- and cross-responsivities. Calculated results for the 3-D case deviate fundamentally from those predicted by the 1-D model. The 3-D model succeeds in explaining measured reduced quantum efficiency of small-area detectors. It also predicts the observed limited effect of diffusion length on self-responsivity and cutoff wavelength. Calculated spectral responses fit data measured on InSb and HgCdTe test arrays extremely well.
