Zusammenfassung:	The spectral response and quantum efficiency of the visible-range photodetectors based on ZnSe and ZnCdSe/ZnSe heterostructures are experimentally studied. The spectral response of the detectors is characterized under various bias conditions. A model of a decrease in the effective height of a reverse-biased Schottky contact under irradiation is used to interpret the internal amplification of the detectors.
