Band Tailing

Band tailing refers to the formation of localized energy states within the band gap of a semiconductor, resulting from structural defects or impurities. These states create an exponential tail extending from the conduction or valence band edges, which significantly influences charge carrier transport and optical properties. / 带尾是指由于结构缺陷或杂质在半导体能带隙中形成的局域化能态。这些能态从导带或价带边缘延伸出指数尾，显著影响载流子传输和光学性质。
