Distribution of nonequilibrium carriers and photoconductivity in inhomogeneous semiconductors
Asryan L. V. , Petrosyan S. G. , Shik A. Ya.
The spatial distribution of nonequilibrium carriers in semiconductors with large-scale inhomogeneities is analyzed. In several cases the photoconductivity of such objects is described by a universal expression which contains only the curvature of the potential of the inhomogeneities and is independent of the carrier lifetime and mobility.
