| Abstract: | The properties of two-dimensional polaron in the polar crystal are expounded by means of a model which takes account of the atomicity of the lattice. The lattice vibration and the interaction between the electron and the lattice displacement are treated by second quantization method. The self-trapped energy, effective mass of the two-dimensional polaron and the temperature dependence of the two-dimensional polaron effective mass are derived. |

| Keywords: | Polaron Polar crystal effective mass |
