dc.description.abstract | Copper oxide thin films were obtained by annealing (temperature ranging between 100 and 450 degrees C) the metallic Cu films deposited on glass substrates by e-beam evaporation. XRD studies confirmed that the cubic Cu phase of the asdeposited films changes into single cubic Cu2O phase and single monoclinic CuO phase, depending on the annealing conditions. The crystallite size is varied between similar to 12 and 31 nm. The lattice parameters of cubic Cu and Cu2O phases are estimated to similar to 3.60 and similar to 4.26 angstrom, respectively. The films with Cu2O phase showed p-type characteristics. The conductivity is decreased linearly with the decreasing temperature (1/T), which has confirmed the semiconductor nature of the deposited films. The calculated activation energy is varied between 0.10 and 0.16 eV. The surface microstructure is changed depending on the variation in the annealing temperature. The poor transmittance of the asdeposited films (<1%) is increased to a maximum of similar to 80% (800 nm) on annealing at 200'degrees C. The estimated direct allowed band gap is varied between 1.73 and 2.89 eV. (C) 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim | - |
