Valence band

在固体中,价带是绝对零温度下电子通常存在的电子能量的最高范围。 半导体带结构价电子与单独的原子结合,与传导电子相反,导电电子可以在材料的原子晶格内自由移动。 在材料的电子带结构图上,价带位于导带的下方,在绝缘体和半导体中通过带隙与其分离。 在金属中,导带没有能量隙与价带分离。 在各种平衡状态下填充电子密度状态。 这里垂直轴是能量,而水平轴是所列材料中特定带的状态密度。 在金属和半金属中,费米能级EF位于至少一个带内。 在绝缘体和半导体中,费米能级位于带隙之内,然而在半导体中,波段足够接近于费米能级,被电子或空穴热填充。 In solids, the valence band is the highest range of electron energies in which electrons are normally present at absolute zero temperature. Semiconductor band structure The valence electrons are bound to individual atoms, as opposed to conduction electrons, which can move freely within the atomic lattice of the material. On a graph of the electronic band structure of a material, the valence band is located below the conduction band, separated from it in insulators and semiconductors by a band gap. In metals, the conduction band has no energy gap separating it from the valence band. Filling of the electronic Density of states in various types of materials at equilibrium. Here the vertical axis is energy while the horizontal axis is the Density of states for a particular band in the material listed. In metals and semimetals the Fermi level EF lies inside at least one band. In insulators and semiconductors the Fermi level is inside a band gap, however in semiconductors the bands are near enough to the Fermi level to be thermally populated with electrons or holes.
