| 摘 要： | 本文利用A、B构成序列有不同排列方式,模拟出晶体、孪晶、准晶和无序的一维结构。应用紧束缚模型,对各结构的电子态进行计算研究,系统地分析比较了各序列的电子能谱、态密度、局域度以及波函数图象,得出准晶体结构是一种新的结构,其电子态不同于晶体、孪晶及无序体的电子态等结论。

| Abstract: | Using the variant sequences made of two basic cell s A and B, we simulateone-dimensional structures of crystal, twin-crystal, quasicrystal and non-crystal in the paper. With the nearest neighbor model, we have investigatedthe electronic states of these structures. Having analyzed and compared theenergy spectrums, the densities of states, the degrees of localization and thewave functions of these structures systematically, we conclude that the struc-ture of quasicrystal is a new one 'and the electronic states of quasicrystalare different from those of crystal, twin-crystal and non-crystal, etc. |
