本文把文献[1,2]的方法推广用于一个更普适的模型,导出了一个适用范围较大的条件,由此出发计算了半无限的第Ⅰ类、第Ⅱ类和Ⅱ-Ⅵ族半导体超晶格的表面等离子谱。结果表明,由于准周期原胞超晶格对于垂直于超晶格轴的截面,不存在反映对称性,因之当表面取在原胞的Fm个不同界面上时(Fm,是Fibonacci数),其表面模式有千姿百态的变化。这种变化有一定的规律,因之这方面的研究将使我们有可能根据理论或实验研究的需要,来设计特定的半无限准周期原胞超晶格,使其表面等离子谱具有期Based on a model a little bit complicated than that in ref. [2] , the mathematical method of ref. [1] was used to yield an universal condition of dispersion. By means of this condition, the surface plasmon spectra of the quasiperiodic semiconductor superlattice of type-I, type-II and II-VI compounds were discussed.The results show that bacause of the break of reflection symmetry in the plane perpendicular to the axis of the superlattice, when the surface is located at the Fm different interfaces of the primary cell, the spectrum of surface plasmon shows a great deal of patterns for each choice of sets of the parameters. (Fm is the Fibonacci number).
