Electrical Properties of CuPC Based Thin Films

Abstract

Electrical properties determine the overall behaviours of electronic and optoelectronic devices. Characterization of electrical properties are important to understand and tailor electronic and optoelectronic devices in desired properties. Understanding the process of producing such devices enables the scientific community to advance current area of electronics and achieve goals leading to cost and energy efficient devices. Hence, we have produced copper doped phthalocyanine (CuPc) based thin film in this study. To assess the electrical properties, capacitance – voltage and conductance – voltage characteristics are measured. Corrective conductance – voltage, corrective capacitance – voltage and serries resistance characteristics are calculated. It is seen that serries resistance, conductance – voltage, capacitance – voltage, corrective conductance-voltage, and corrective capacitance-voltage results exhibit frequency dependent behaviours. These characteristics are highly dependent on interface states. We conclude that intrinsic properties have enormous effect on the electrical properties of the CuPc thin film.
