摘　　要：用实空间方法,借助一维模型研究了铁电体和半导体集成体系的晶格振动行为,讨论了一维链表面模、界面模,长程作用下的布里渊区边界模等的振动特性,解释了ＧａＡｓ/ＳｒＴｉＯ３体系的拉曼谱图．Using the real space method the lattice vibration behavior of integrated system of ferroelectrics and semiconductor with the aid of one-dimension model was investigated. The vibration characteristics of the surface mode, the interface mode and the mode in the boundary of Brillouin zone under the long range interaction was discussed. The Raman spectrum of GaAs/SrTiO3 was explained quantitatively in terms of the authors' calculation.
