摘要
采用紧束缚方法计算了生长在GexSi1-x合金(001)面上的应变GaAs层以及生长在Si(001)面上的应变超晶格(Si2)4/(GaAs)4的电子能带结构。讨论了应变对电子能带结构的影响.
The electronic band Structures of strained strained GaAs layers grown on GexSi1-x alloys in (001) plane and strained superlattices(Si2)4/(GaAs)4 grown on Si substrates in (001)plane are calculated in tight-binding frame. The effects of strains on the electronic band structures are discussed.
