  • Lateral photodetector of improved sensitivity
    Patent number: 3971057
    Abstract: A lateral photodetector of improved sensitivity and method of making the e. The photodetector consists of semiconductive wafer, having a transparent layer of metal deposited on its front face to form a Schottky barrier. A negative bias is applied to the Schottky barrier to form a depletion region in the wafer. A low resistivity layer is formed on back of the wafer to which four signal electrodes are attached. Before forming the cell, the semiconductor wafer was exposed to nuclear radiation to increase the responsivity of the cell.
