Melt growth, characterization and properties of bulk In2O3 single crystals

► Truly bulk In2O3 single crystals were grown from the melt for the first time. ► Annealed crystals have electrical properties typical for semiconductors. ► Annealed crystals are transparent in the visible (from 440 nm) and IR spectra. ► The crystals are chemically stable at operating temperatures of epitaxial methods.
