Abstract: A NTCDA single crystal is used as a photoelectric current multiplier layer, and Au thin films are formed as electrodes on the opposite surfaces of the multiplier layer by a vapor deposition method to form a sandwich type cell. When a voltage is applied to the NTCDA single crystal by the electrodes from a dc power source and a monochromatic light is applied, a multiplied photoelectric current flows between the electrodes. A rise of this element at light-on is considerably faster than when a vapor-deposited layer is used as a photoelectric current multiplier layer to permit a faster response.
