抄録
Annealing was performed on GaAs single crystals covered with Ga2O3 powder under reduced pressure. The annealing at 820°C produced a thin film of about 2 μm on the crystal surface. The film was confirmed to be an oxide substance containing β-Ga2O3. The Hall effect measurement revealed that, with oxide powder, the surface region where the change of electrical properties can be minimized to a few microns while without oxide powder, this figure increases to over 200 μm. This is explained by the capping effect of the film to prevent a thermal decomposition of GaAs.
