The optical band gap energy was determined by spectral data of transmittance and absorbance to be 2.04eV. The electrical conductivity of grown films was measured around （1：1 × 10^-5Ω^-1cm^-1） at 300K. Thermoelectric power measurements of the film were carried out. Furthermore, the properties of these films are compared with properties of Cu2O obtained by other methods.展开更多
