Abstract
A process for fabricating Al-doped β-Ga2O3 thin films of the (AlxGa1−x)2O3 composition by plasma-enhanced chemical vapor deposition has been studied for the first time. High-purity gallium metal, aluminum iodide (AlI3), and high-purity oxygen were used as precursors. Low-temperature plasma at a reduced pressure (0.01 torr) was the initiator of chemical transformations between the reactants. The plasmaenhanced deposition process was studied by optical emission spectroscopy in the range of 180–1100 nm. The obtained thin films of the (AlxGa1−x)2O3 system with the amount of the Al2O3 phase up to 20% were studied by various analytical methods.
