Paper Abstract

The structural and transport properties of evaporated fluorinated copper phthalocyanine organic field effect transistors with polymer dielectric layer polycarbonate were reported. A high field effect mobility of 5.7×10-3 cm2/ Vs, an on/off ratio of 104 and a threshold voltage of 5V were obtained under atmospheric conditions. χ-ray diffraction and atomic force microscopy show a clear correlation between the morphology and structure of F16CuPc film on the polycarbonate dielectric surface. Temperature dependent measurements of the mobility were performed. X-ray diffraction results show that the crystallinity and orientation of F16CuPc on polycarbonate thin film are enhanced with increasing surface temperature.
