| 摘 要： | 对卤族桥接含金属离子的混合价化合物(HMMC)的研究,近年来引起人们广泛的兴趣,因为这种物质具有准一维电荷密度波基态,能生长成良好的单晶,是研究低维量子理论的一种良好的样品,具有很大潜在的应用前景.本文根据作者所发展的处理电子-声子作用的方法;提出了一个HMMC被光激发后的晶格驰豫模型,讨论了其对光感应吸收的影响,并在此基础上,计算了光感应吸收峰,较之其他模型所算得的结果更符合实验事实。

| Abstract: | The nonlinear lattice relaxation duo to light exciting in quasi-one-di-mensional mixed-valence metal compounds is investigated using a model which describesthe relaxation process more reasonably. A possible mechanism of nonlinear latticerelaxation is presented and the photo-induced absorption peaks which including theeffect of rolaxating are calculated and comparing with experimental data is made. |
