摘要: 对具有在位势且含杂质的一维双原子链的晶格振动方程组进行求解,得到了局域振动的解析解,给出了在位势对局域振动影响的基本特征,并简要讨论了对称局域模的存在形式.
关键词: 杂质, 在位势, 局域模
Abstract: The lattice vibration equations of a diatomic chain with an impurity atom and on-site potential are solved.The analytic solutions of local vibration are obtained.The basic features of the effect of on-site potential on the local vibration are given,and the existence forms of symmetric localized mode are also discussed.
Key words: impurity, on-site potential, localized mode
