Photoelectric Conductivity in Semi-Conductors

Abstract

The equations relating the photocurrent to field strength, intensity of illumination, quantum efficiency, and electron and hole mobilities and concentrations in semiconductor crystals, are derived for the case when both holes and electrons are present. It is shown that in contrast to the case of induced conductivity in insulators, the measurement of time constant and of deviation from Ohm;s law does not yield sufficient information to determine either hole or electron mobility.
