Recently, doping with Cu atoms has attracted increasing attention because of its promising potential applications in semiconductor devices. In this study, CZO films have been prepared on glass substrate by ultrasonic spray method using zinc acetate, copper acetate and ammonium acetate aqueous solution as precursors. The electrical and optical properties of the prepared CZO films and the ZnO/CZO diodes were discussed. This study contains two parts. Firstly, this study prepared CZO films with different Cu concentration from 10% to 30%. The electrical and optical properties of CZO films were investigated and compared by many measurements. Secondly, ZnO/CZO diode was fabricated on ITO substrate. The I-V curve of the device was investigated with or without being exposed to the magnetic field.
