Influence of energy bands distortion on non-steady-state photo-induced electromotive force in semiconductors

摘要

A theory of the non-steady-state photo-induced electromotive force in bipolar semiconductors accounting for the boundary conditions in a metal-semiconductor junction and distortion of energy bands near semiconductor surface is developed. It is shown that the surface potential can change essentially both the amplitude and the phase-frequency characteristic of the photo-induced electromotive force.
