Abstract

In the presented paper, p-type cuprous oxide (p-Cu2O) thin films of various thicknesses (d = 2 µm; 3 µm and 5 µm) were obtained by chemical deposition method. The mechanisms of the influence of the thickness of the obtained p-Cu2O thin films on the optical transmission and absorption spectra were analyzed. A systematic red shift of the fundamental optical absorption edge toward lower photon energies, within the range of E = 0.37–0.44 eV, has been observed with increasing sample thickness. This phenomenon is primarily attributed to the enhancement of crystalline quality, accompanied by a reduction in the density of surface defects and a suppression of sub-bandgap optical transitions associated with localized defect states.
