An all organic field-effect transistor based on ordered film of copper phthalocyanine

Abstract

Copper Phthalocyanine (CuPc) has been attracted particular attention recently due to its outstanding chemical stability and photo/electrical properties. An all-organic field-effect transistor (OFET) based on ordered CuPc was investigated. Ideal transistor behavior was observed in the OFET using copper phthalocyanine (CuPc) as the semiconductor layer and polymethylmethacrylate as the insulator layer. The ordered CuPc layer was evaporated by previous method (Thin Solid Films 347 (1999) 299). The results of the OFET demonstrated that the channel carrier mobility and switching ratio were at about 0.008 cm2V-1s-1 and 103, respectively.
