In addition, basing on the tight-binding model of the single electron and transfer matrix method, we study the charge transfer properties of Fibonacci sequence and discuss specially the dependent of electronic transmission on energy and the length of the sequence. We find some resonant peaks can survive in relatively longer Fibonacci sequences than random sequences, which also implies there are long-range correlations in Fibonacci sequences.

从Anderson紧束缚模型出发，采用传输矩阵方法研究了Fibonacci序列的电子输运特性，讨论了输运系数对能量及其序列长度的依赖关系，发现随着序列的长度增加，具有好的透射性的电子态数量有所减少，但相对于随机序列而言，共振能态可以在更长的序列中存在，进一步证明了Fibonacci序列中存在有较强的长程关联行为。
