Abstract
Low-temperature oscillations in the photoconductivity of semiconductors are discussed. It is shown that oscillations will be observed if the probability for energy relaxation with optical phonons exceeds both the probability of carrier recombination and the energy-relaxation time for acoustic phonons. The oscillation shape is studied for momentum relaxation with acoustic phonons and with ionized impurities for the case in which interelectronic collisions can be neglected and when an account of these collisions leads to the establishment of an electron temperature.
