周期結構中光學聲子的色散關系

摘要：本文詳細的討論了1些周期結構的色散關系。首先本文利用牛頓定理推導了1個原胞內(nèi)含有2個原子的1維和2維周期性結構的色散關系，接著利用黃昆方程和靜電學理論討論了Ａ／Ｂ型周期結構，Ａ／Ｂ／Ｃ型周期結構的光學聲子的色散關系和Ａ／Ｂ型周期結構中含缺陷的宏觀界面光學聲子的色散關系。

關鍵詞：超晶格；光學聲子；色散關系；周期結構；

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.

Key word: Superlattice; Optics phonon; Dispersion relations; Periodic structure;
