Scientific paper

The finite difference method has been used to solve the one-dimensional carrier transport equation in order to study the surface recombination velocity s in (Hg, Cd)Te. This numerical approach was applied to the analysis of typical configurations and was implemented in the reduction of photoconductive lifetime data to experimentally determine s in (Hg, Cd)Te. Contour maps of effective minority carrier lifetime and surface recombination velocity were used to study the spatial distribution and relationship between bulk and surface recombination. Experimentally, the PC lifetime and surface recombination velocity have been mapped on bromine-methanol polished surfaces and on anodic oxide passivated surfaces for (Hg, Cd)Te produced both by the solid state recrystallization (SSR) and the traveling heater methods (THM). The anodic oxide passivation has been observed to alter the magnitude and distribution of the PC lifetime measured, and it reduced the surface recombination velocity.
