Paper Abstract

The results of the investigations of the injection photodiodes p-i-n structures, based on high-resistivity semiconductors, compensated by deep-level impurities, are presented. Mechanisms of the photoelectric injection amplification are discussed, which consists in the direct influence of light on the charge currier distribution parameters in the semiconductor volume. The diodes are shown to by sensitive in a broad spectral range. The integral sensitivity of photodetectors of this type is much higher than that of injectionless devices. The physical mechanism of the injection amplification of photocurrent in mercuri- compensated and indium antimonide under the effect of the middle IR-wavelength band electromagnetic radiation has been studied both theoretically and experimentally.
