  • Multiplication device comprising resin-dispersed organic semiconductor film and method for producing the same
    Publication number: 20030180998
    Abstract: A resin-dispersed organic semiconductor layer (3) is formed on a lower electrode (2) of an ITO transparent electrode formed on a glass substrate (1). An upper electrode (4) of a gold deposited film is formed on the resin-dispersed organic semiconductor layer (3). The resin-dispersed organic semiconductor layer (3) is formed by spin-coating a dispersion liquid prepared by mixing a perylene pigment and polycarbonate in a THF solvent and drying the coating. By applying a voltage by means of the electrodes (2, 4) and by irradiating the resin-dispersed organic semiconductor layer (3) with light, a multiplied light irradiation-induced current flows.
