Abstract

The paper proposes a method for fabricating gallium oxide substrates from bulk β-Ga2O3 crystals by the cleavage method. Layers of β-Ga2O3, β-(AlxGa1–x)2O3 and structures of β-Ga2O3/β-(AlxGa1–x)2O3 are grown on the prepared substrates by the MOCVD method. The surface morphology of the layers and growth regimes are analyzed. The fundamental possibility of using gallium oxide substrates obtained by the cleavage method for the subsequent epitaxy is shown.
