Indirect bandgap — In semiconductor physics, an indirect bandgap is a bandgap in which the minimum energy in the conduction band is shifted by a k vector relative to the valence band. The k vector difference represents a difference in momentum.Semiconductors that… … Wikipedia
Wide bandgap semiconductors — are semiconductor materials with electronic band gaps larger than one or two electronvolts (eV). The exact threshold of wideness often depends on the application, such as optoelectronic and power devices. Wide bandgap materials are often utilized … Wikipedia
Direct bandgap — In semiconductor physics, a direct bandgap means that the minimum energy of the conduction band lies directly above the maximum energy of the valence band in momentum space. In a direct bandgap semiconductor, electrons at the conduction band… … Wikipedia
