Abstract
Electron-acceptor properties of alpha-, beta-, gamma-, and delta-Ga2O3 are studied by ESR spectroscopy of paramagnetic anthraquinone complex es. It is shown that the formation of Lewis acid sites on the dehydrox ylated surface of these oxides is governed by peculiarities of their c rystalline structure and is determined by the existence of Ga3+ cation s in tetrahedral positions.
