چکیده انگلیسی
In this work, CuxO thin films were obtained by air annealing of copper thin films deposited on glass substrates using thermal evaporation method by Glancing Angle Deposition “GLAD” technique. The copper was sculptured into a zigzag shape, which presents two columns with inclined angles +γ and âγ where γ is the deposition angle between the incident flux and the substrate normal. Morphological, structural, optical and electrical properties of the obtained thin films were investigated using X-ray diffraction (XRD), UV-Vis-NIR Spectroscopy and electrical resistivity measurements. The XRD patterns revealed that thin films deposited at different incident angles are mainly crystallized in Cu2O cubic phase characterized by the preferential orientation along (111) plane. The optical parameters were calculated from the analysis of the transmittance and reflectance spectra in the wavelength range 300-1800â¯nm. The absorption coefficient exceeds 105â¯cmâ1 in the visible and NIR spectral ranges. Direct band gap energy increases from 2 to 2.54â¯eV with deposition angle. The in-plane birefringence and the anisotropic resistivity of the Cu2O films were also studied. Their maxima were obtained at incident flux angle of γâ¯=â¯Â±60°. Therefore, the GLAD technique is a promising way to create zigzag nanostructures with enhanced anisotropic properties.
