PHOTOSENSITIVE SEMI-CONDUCTOR DEVICE

摘要

A photosensitive semi-conductor device for use as a target of camera tubes. It has a semi-insulating layer formed on that side of a semi-conductor substrate which is impinged by light photons or energetic electrons. The semi-insulating layer is charged in accordance with the incident light photons or energetic electrons, and the electric field set up across the semi-insulating coating layer by the bombardment of light photons and energetic electrons has an effect of controlling the motion of minority carriers to automatically control the input-output photoelectric conversion gain of the photosensitive semi-conductor device.
