The fabrication and operating mechanism analysis of copper-phthalocyanine organic thin film transistor

Abstract

In order to make the operating characteristics of OFET device better, we used CuPc to fabricate organic thin film transistor with five layers structure of Au/ CuPc / Al / CuPc /Au with vertical conductive channel. Tested basic operating characteristics and analyzed relation between device structure and operating characteristics of it. The experimental results showed that drive voltage was low and i-v characteristics was unsaturated. Grid voltage has great control effect on operating characteristics of organic static induction transistor. Therefore, we can improving the driving voltage and switching characteristics of organic transistor by reasonable design the device structure to form vertical conductive channel.
