摘要：
A photoconductive type sensor which comprises a photoconductive layer having a photosensing region. A pair of main electrodes are provided which are disposed on the photosensing region of the photoconductive layer. The sensor also comprises a gate electrode for applying a bias voltage to the photosensing region. The gate electrode provides a bias of one polarity so as to suppress the generation of a channel in the photosensing region.
