Open Access Theses & Dissertations
Gallium Oxide thin films were produced by sputter deposition by varying the substrate temperature (Ts) in a wide range (Ts=25-800 oC) and under variable deposition time. The structural characteristics and optical properties of Ga2O3 films were evaluated using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectrometry (EDS), Rutherford backscattering spectrometry (RBS) and spectrophotometric measurements. The effect of growth temperature is significant on the chemistry, crystal structure and morphology of Ga2O3 films. XRD and SEM analyses indicate that the Ga2O3 films grown at lower temperatures were …
