Paper Abstract

Two-dimensional diffusion model was used to analyze the charge-carrier diffusion process in the photosensitive film of photovoltaic HgCdTe IR FPA detectors with a continuous (without mesa-isolation of pixels) absorber layer. Some applications of the model and its inaccuracies are considered. Estimates of the local charge-carrier diffusion length values in the FPA regions under and outside photodiodes were obtained on the basis of spot-scan data.
