| Summary: | Thin ZnO films on silicon and quartz substrates were obtained from a film-enriched ethanolic solution based on Zn(NO3)2⋅6H2O and salicylic acid. The effect of salicylic acid on the processes occurring in the film-forming solution was studied by IR spectroscopy, proton-magnetic resonance, and viscometry methods. The formation of zinc salicylate nitrate in an ethanol solution is established, where salicylic acid exhibits a monodentate property in the carboxyl group. Thermal formation of zinc oxide was determined by thermal analysis and X-ray diffraction. The analysis of optical and electrophysical characteristics of ZnO films was carried out using spectroscopy, ellipsometry and also a block for measuring the electrophysical properties of thin-film materials. It was found that ZnO films were semiconductors of the electronic type, characterized by an optical band gap of 2.91-3.21eV, a surface resistance of 109-106 Q. and transparency coefficients in the visible spectral range of 0.80-0.96. It was shown that as the thickness of the ZnO films increased the resistance decreased. |
