dc.description.abstract【中文摘要】 用线性Muffin-tin轨道(LMTO)能带计算方法对晶格匹配的超晶格系统(ZnS)n/(Si2)n(110)(n=2~5)进行超原胞自洽计算.在此基础上,用冻结势方法计算了该超晶格系统的价带带阶;用四面体方法计算了该系统的联合态密度.结果表明,该超晶格系统的价带带阶约1.5eV.还讨论了(ZnS)n/(Si2)n(110)超晶格系统的光学性质. 【英文摘要】 Supercell self-consistent calculation of band structure of (ZnS)n/ (Si2 )n (110)(n=2~5) has been performed by means of Linear Muffin-tin Orbitals(LMTO) method. The valence-band offsets of such systems are calculated by frozen potential method and their Joint density of states has been computed by tetrahedron method. The results show that the (ZnS)n/(Si2 )n (110) superlattices have a large valence-band offset and their optical properties integrate excellent optical properties of bulk ZnS and that of Si, and ...zh_CN
