摘　　要：在转移模型基础上，考虑格点间的相互作用对座能量的影响，提出转移－ 混合模型在该模型下 Ｆｉｂｏｎａｃｃｉ 点阵有与座模型、转移模型等明显不同的电子能谱结构，随座能量的差异，可以是４ 主带和５ 主带结构，并稳定于５ 主带结构，还找到了主带进一步分裂为子带的规则点阵电子波函数广泛存在自相似性。The transfer-mixture model of Fibonacci lattices is presented.Considering the effect of the nearest neighbor interaction on site-energy, the electronic properties of Fibonacci lattices is studied by the tight-binding method.The calculation results show that the gross bands are 4-band structure and 5-band structure except 3-band structure which is well-known. The subband branching rules and the self-similarity of the module of wave-vector are also obtained.

关 键 词：Fibonacci点阵 能带结构 分支规则 自相似性
