摘要
只考虑最近邻原子间的简谐力互作用 ,应用Dyson方程推导了纳米一维双原子晶体颗粒的位移 位移格林函数 ,并在此基础上研究了其声子结构。
The displacement-displacement Greens function of one dimensional diatomic nanocrystal was deduced with Dysons equation, including the nearest neighbor harmonic interaction only. On the basis of the theory of Greens function, the phonon structure is studied.
