Impacts of oxygen radical ambient on structural and optical properties of (AlGa)2O3 films deposited by pulsed laser deposition

We report on the impacts of oxygen radical ambient for (AlGa)2O3 films grown on sapphire substrates by pulsed laser deposition (PLD). All the films showed a monoclinic crystal structure and high transmittance in the ultraviolet and visible wavelength range. The surface roughness was less than 3 nm f...
