許多半导性固态物质,其电导率和絕对温度之同有如下的关系: σ=σ_0exp- △E/2kT式中△E为本征牛导体的电子活化能(或称禁带宽度)。半导体的这种电学特性可用能带理論闡明。但是,近来許多非晶形半导体(液态半导体,聚合物牛导体等)材料的发现,为能带理論的应用造成某些困难。約飞指出,为了揭露导致半导性的内在原因,研究物质内部在 Many semi-conductive solid materials, the conductivity and absolute temperature are the same as follows: σ = σ_0exp- △ E / 2kT Where △ E is the intrinsic activation energy of cattle conductor (or band gap). This electrical properties of semiconductors can be used to band theory. However, the recent discovery of many amorphous semiconductors (liquid semiconductors, polymer cowries, etc.) materials poses some difficulties for band theory applications. Yue Fei pointed out that in order to expose the inherent causes leading to semiconductors, the study of the material internal
