【Abstract】 Organic static induction transistors (OSIT) with schottky gate electrode of Au/CuPc/Al/CuPc/Au sandwich structure are fabricated by the method of vacuum evaporation and the evaporated films of organic semiconductor copper phthalocyanine (CuPc) as the active layers.The conductor channel of OSIT perpendicular to the surface of the CuPc film is largely shorter than that of metal oxide semiconductor field effect transistor (MOSFET), which avails to overcome the shortcoming of electrical characteristics of organic semiconductor.The experimental results manifest the low driver voltage and no saturated current voltage characteristics of OSIT.The working properties depend on the gate bias voltage and the structure of pectinate Al electrode.Good static and dynamic characteristics of OSIT are obtained by properly designing the structure of pectinate Al electrode.更多还原
