Abstract

Photogenerated current at 77K, when the transparent gate of an Hgl-xCdxTe(x=0.29) and InSb p-channel MISFETs is illuminated with infrared radiation, have been evaluated theoretically as a function of gate voltage. To process of excitation are considered, namely, an electron-hole pair generation across the bandgap in the depletion layer of the field induced junction and an electron excitation through interface states at the semi-conductor-SiO2 interface. The photocurrent is primarily due to the later process. For sake of comparison, the drain-source current without illumination has also been calculated as function of gate voltage.
