| Abstract: | 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. |

| Keywords: | Exciton Temperature Polar crystal Effective mass |
