摘要
Organic held-effect transistors that employ copper phthalocyanine (Cu-Pc) as the semiconducting layer can function as p-channel accumulation-mode devices. The charge carrier mobility of such devices is strongly dependent on the morphology of the semiconducting thin film. When the substrate temperature for deposition of Cu-Pc is 125 degrees C, a mobility of 0.02 cm(2)/V s and on/off ratio of 4 x 10(5) can be obtained, These features along with the highly stable chemical nature of Cu-Pe make it an attractive candidate for device applications.
