چکیده انگلیسی
This paper reports high-temperature (305-523Â K) electrical studies of chemical bath deposited copper (I) selenide (Cu2âxSe) and copper (II) selenide (Cu3Se2) thin films. Cu2âxSe and Cu3Se2 have been prepared on glass substrates from the same chemical bath at room temperature by controlling the pH. From X-ray diffraction (XRD) profiles, it has been found that Cu2âxSe and Cu3Se2 have cubic and tetragonal structures, respectively. The composition of the chemical constituent in the films has been confirmed from XRD data and energy-dispersive X-ray analysis (EDAX). It has been found that both phases of copper selenide thin films have thermally activated conduction in the high-temperature range. In this paper we also report the variation of electrical parameters with film thickness and the applied voltage.
