POPOVYCh N. Formation processes and basic optical properties of zinc tiogallate thin films

Zinc tiogallate thin films. The aim of the work: to create an optimal technology of formation of zinc tiogallate thin films, to determine their basic optical parameters and to study an influence of thermal and laser processing on their optical properties and structure. The methods of the investigations are mass-spectrometry, quantum chemical calculations, the investigation of optical absorption spectra, thermal and laser annealing. The character of zinc tiogallate evaporation is established. The model of growth of a condensate on a substrate is developed. The technology of preparing of thin film by impulse laser evaporation, magnetron sputtering and quaziequilibrium thermal methods is developed. A dispersion of refraction index and band gap of zinc tiogallate films are determine. The new type of optical antirefraction and protect coating are developed. The introducing is planning. An area of application is optoelectronics.
