PHOTOELECTRIC CURRENT MULTIPLIER USING MOLECULAR CRYSTAL AND PRODUCTION METHOD THEREFOR

摘要

A 167μm−thick NTCDA single crystal(2)is used as a photoelectric current multiplier layer,and Au thin films are formed in thickness of 20 nm as electrodes(4,6)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(2)by electrodes(4,6)from a dc power source(8)and a monochromatic light is applied,a multiplied photoelectric current flows between the electrodes(4,6).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.
