In this paper, we report on the successful fabrication of β-Ga2O3 thin films by spray-pyrolysis technique. We provide the data on the dependence of the quality of the β-Ga2O3 films on the regimes and parameters of fabrication. Scanning electron microscopy, atomic force microscopy and optical spectroscopy are used to analyze film properties. X-ray diffraction phase analysis of the films after heat treatment at 900°C confirms the formation of β-Ga2O3 crystallites.
