Band gap — This article is about solid state physics. For voltage control circuitry in electronics, see Bandgap voltage reference. In solid state physics, a band gap, also called an energy gap or bandgap, is an energy range in a solid where no electron… … Wikipedia
Direct and indirect band gaps — In semiconductor physics, the band gap of a semiconductor is always one of two types, a direct band gap or an indirect band gap. The band gap is called direct if the momentum of electrons and holes is the same in both the conduction band and the… … Wikipedia
Semiconductor — Citations missing|date=March 2008A semiconductor is a solid material that has electrical conductivity in between a conductor and an insulator; it can vary over that wide range either permanently or dynamically. [. They are used in many… … Wikipedia
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
Metal-induced gap states — In bulk semiconductor band structure calculations, it is assumed that the crystal lattice (which features a periodic potential due to the atomic structure) of the material is infinite. When the finite size of a crystal is taken into account, the… … Wikipedia
Electronic band structure — In solid state physics, the electronic band structure (or simply band structure) of a solid describes ranges of energy that an electron is forbidden or allowed to have. It is due to the diffraction of the quantum mechanical electron waves in the… … Wikipedia
Intrinsic semiconductor — An intrinsic semiconductor, also called an undoped semiconductor or i type semiconductor, is a pure semiconductor without any significant dopant species present. The number of charge carriers is therefore determined by the properties of the… … Wikipedia
