周期結(jié)構(gòu)中光學(xué)聲子的色散關(guān)系
摘要：本文詳細(xì)的討論了1些周期結(jié)構(gòu)的色散關(guān)系。首先本文利用牛頓定理推導(dǎo)了1個(gè)原胞內(nèi)含有2個(gè)原子的1維和2維周期性結(jié)構(gòu)的色散關(guān)系，接著利用黃昆方程和靜電學(xué)理論討論了Ａ／Ｂ型周期結(jié)構(gòu)，Ａ／Ｂ／Ｃ型周期結(jié)構(gòu)的光學(xué)聲子的色散關(guān)系和Ａ／Ｂ型周期結(jié)構(gòu)中含缺陷的宏觀界面光學(xué)聲子的色散關(guān)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.
Key word: Superlattice; Optics phonon; Dispersion relations; Periodic structure;
