摘　　要：本文计及晶格的原子结构讨论了二维Frenkel激子的性质。用二次量子化方法处理晶格振动及其与激子的相互作用,导出了二维Frenkel激子的自陷能以及它的有效质量与温度的关系。The properties of a two-dimcnsional Frenkel exciton are expounded by means of a model which takes account of the atomicity of the lattice.The lattice vibration and the interaction between the exciton and the tatticc displacement are treated by second quantization method. The self-trapped energy and the temperature dependence of the effective mass of the two-dimensional Frenkel exciton are derived.

关 键 词：激子 温度 晶体 有效质量 相关性
