摘要: A method is disclosed for fabricating monocrystal material with the bandgap width exceeding 1.8 eV. The method comprises the steps of processing a monocrystal semiconductor wafer to develop a porous layer through electrolytic treatment of the wafer at direct current under UV-illumination, and epitaxially growing a monocrystal layer on said porous layer. Growth on porous layer produces semiconductor material with reduced stress and better characteristics than with the same material grown on non-porous layers and substrates. Also, semiconductor device structure comprising at least one layer of porous group III material is included.
