Electrical properties study of Copper Phthalocyanine ( CuPc) thin films

Abstract

(Abstract) Thin film of copper phthalocyanine has been deposited onto glass substrates by using thermal evaporation technique at room temperature. The dark electrical resistivity ( ) and thermoelectric power measurement were carried out at different temperatures in the range (293-503)K. The temperature dependence of current density allows the calculation of thermal activation energy that was (0.79)eV. Room temperature current-voltage characteristics measurement, using Hull effect allows the calculations of some essential parameters such as the electron mobility and concentration of electrons .
