  • 用连续介电模型研究了有限厚度四层异质结构的表面和界面光学声子模。精确得到本征失量、色散关系和面电荷密度。前人关于介电平板、双层、三层以及无限四层结构等所有已得结果,都可从此文普遍关系重新推出。另外,还给出了有限阶梯量子阱等有趣而实用结构的色散关系及其数值显示。本研究可视为文献[8]的推广。
    We have used the dielectric-continuum model to study the surface and interface optical-phonon modes in a four-layer heterostructure with finite thickness. The eige-nvectors, the dispersion relation and the interface charge densities are obtained. All the previous results for a dielectric slab, bilayer, trilayer and infinite four-layer he-terostructures can be reded-iced from our general relation for a finite four-layer he-terostructure. The dispersion relations and their numerical illustration for some inte-resting and practical structures such as a finite step-quantum-well are also given. This work can be regarded as a generalization of the formalism in reference [8].
