周期结构中光学声子的色散关系

摘要：本文详细的讨论了1些周期结构的色散关系。首先本文利用牛顿定理推导了1个原胞内含有2个原子的1维和2维周期性结构的色散关系，接着利用黄昆方程和静电学理论讨论了Ａ／Ｂ型周期结构，Ａ／Ｂ／Ｃ型周期结构的光学声子的色散关系和Ａ／Ｂ型周期结构中含缺陷的宏观界面光学声子的色散关系。

The dispersion relations of optics phonon In periodic structure

Abstract:Some dispersion relations of optics phonon in periodic structure are studied in detail in the article.The first, the dispersion relations of optics phonon in one-dimensional and the two-dimensional periodic structure which is maked up of cellulars which contain two atoms are studied by Newton’theory.Then ,dispersion relations of optics phonon in A/ B periodic structure amd A/B/ C periodic structure and the macro- surface dispersion relations of optics phonon in A/ B periodic structure contains defact are studied by the Huang Kun equationand and electrostatics theory.
