Paper Abstract

The abnormal photoelectric properties of Si-MIS structures, such as a significant photo-emf signal in the state of enhancement and a drop of the local photo-emf in inversion, were investigated with integrate and local photoelectric measurements. It has been established that the reason for the significant photo-emf signal in enhancement and the related features of the photoelectric properties of the structure is the photosensitivity in the region away from the electrode associated with a nonuniform distribution of electrically active defects. It has been demonstrated that the nonuniformity in surface potential may result in a drop of the local photo-emf in inversion. A conclusion has been made that the redistribution of nonequilibrium carriers along the boundary must be taken into account in constructing equivalent circuits of actual MIS structures.
