Özet

The effect of the oxygen flow rate on the characteristics of the CuO films have been investigated for their potential applications. XRD and Raman measurement results show that the crystal phases of the deposited films are strongly influenced by the oxygen flow rate. With oxygen flow rate, the (200) diffraction peak of cuprite disappears, and peak values observed in Raman spectra change. Further, the optical properties of the CuO films are found to be reliant on the flow rate as indicated by the optical transmittance and reflectance measurements. Moreover, the change in oxygen flow rate has a strong impact on the surface morphologies and thicknesses of the copper oxide films as corroborated by scanning electron microscopy images. From the temperature-dependent electrical characteristics, the thermally activated conduction and multi-phonon hopping mechanism are found to be responsible for the electrical transport at the high and low temperature regimes, respectively.
