摘要
在单电子紧束缚近似下,研究几种典型的一维非周期序列,通过数值计算分析它们的电子性质.从波函数的空间分布情况和局域长度的取值范围两方面比较分析了这些序列在电子局域性质上的差异.结果表明,伽罗华序列的局域性最强,图厄-莫尔斯序列的扩展性最强.
Several typical one-dimensional aperiodic sequences are studied in the framework of the tightbinding approximation. The electronic properties are numerically calculated and analyzed. From the spatial distribution of the wave function and the range of the localization length, the differences of electronic properties among these sequences are compared. The results show that Galois sequences is the most localized while the Thue-Morse sequence is the most extended.
