Imaging ellipsometry of cobalt oxide thin films for the fabrication of Co3O4/CeO2 diodes by spin-coating
Original language description
Cobalt oxide (Co3O4) and Gd doped cerium oxide (CeO2) thin films were synthesized by a spin coating process to obtain a p-n junction. The surface of both films was characterized by spectroscopic imaging ellipsometry (SIE). The uniformity of the ellipsometric angles was analyzed by a principal component analysis (PCA). The variability of the spectra composing the SIE images led to an estimated error of 10.5 % on the determined thickness and optical parameters. The measured energy band gap of Co3O4 films with optimized deposition conditions was 1.79 eV. The heterostructure TCO/CeO2:Gd/Co3O4 formed a n-p junction exhibiting diode behavior, with a rectification factor of 1.57, shunt conductance of G = 1.75 mS cm-2 and series resistance of R = 46.54 Omega cm2, showing the feasibility of this heterojunction for diode devices.
