| 摘 要： | 本文用半经验紧束缚法研究了(ZnSe)_n/(Ge)_(2m)(100)超晶格,计算了其能隙随层厚的变化,其结果能说明超晶格体系的准二维特性,表明(7,7)超晶格已足以模拟异质界面问题,并指出(ZnSe)_n/(Ge)_(2m)(100)超晶格的禁带中很可能存在界面态。

| Abstract: | In this paper, a semi-empirical tight-binding theory is applied to the research of (ZnSe)n/(Ge)2m(100) superlattice. The variation of energy gap with layer thickness is calculated. The result shows the quasi-two-dimension feature of superlattice system, and that (7,7) superlattice can adequately simulate the interface problem of heterojunction. This paper predicts that interface states may exist in the energy gap of (ZnSe)n/(Ge)2m(100) super-lattice. |
