Synthesis, Investigation and Neural Network Modeling of the Properties of Sol-Gel ITO/ZnO and ITO/ZnO:Mg Structures

Abstract

The ITO/ZnO and ITO/ZnO:Mg bilayer structures were fabricated by the sol-gel method and their structural and photoelectric properties were experimentally studied. It is shown that, compared with ZnO and ZnO:Mg films without an ITO sublayer, the morphology changes noticeably and the band gap decreases. The I–V characteristics of obtained structures were analyzed in the dark and under the influence of optical radiation of different wavelengths. Using artificial neural networks, their spectral photosensitivity was modeled.
