Structural and electronic characteristics of Fe-doped β-Ga2O3 single crystals and the annealing effects

As capture traps, Fe impurities were intentionally incorporated into beta-gallium oxide (β-Ga2O3) crystals to compensate for unintentional n-type conductivity for applications of semi-insulated single-crystal substrates with high-performances. The systematic investigations are performed to comprehend the influence of the Fe addition on the structural, optical, electronic properties of the β-Ga2O3 crystal, and the annealing effect by using a...
