Abstract

The electron diffusion length is deduced in n-indium tin oxide/p-InP heterojunctions by a short-circuit photocurrent technique. The technique involved the nonlinear least-squares fit of the photocurrent and junction capacitance to a simple model. The absorption coefficient of the monochromatic light is also produced by the fit. This produces an electron effective diffusion length in the p-InP which varies from about 1.0 μm for highly absorbed light up to about 8.0 μm for deeply penetrating light.
