基于DFT计算，我们研究了各种类型的ASiSL，它们是由不同宽度的ASiNR构成的周期性重复的结。 ASiSL 的能带结构由超晶格的尺寸和应变调节。窄纳米带和宽纳米带的长度在 ASiSL 电子结构的调节中发挥着有趣的作用。它可以改变能带结构，并改变超晶格的局域和色散态的分布。随着染色量的增加，ASiSLs的相关能隙会发生变化，与组成纳米带的能隙显着不同。
Based on the DFT calculations, the various types of ASiSLs, which are the periodically repeated junctions made of ASiNRs with different widths, have been investigated. The band structures of ASiSLs were modulated by the size and strain of superlattices. The length of the narrow and wide nanoribbons plays interesting roles in the modulation of the electronic structures of ASiSLs. It could alter the band structure, and modify the distribution of the localized and dispersive states of superlattices. With the stain increased, the related energy gaps of ASiSLs will change, which are significantly different with that of the constituent nanoribbons.
