采用线性组合算符方法,研究与表面光学声子耦合强、与表面声学声子耦合弱的声学形变势表面极化子的温度效应.对KI晶体的数值计算结果表明:振动频率、有效质量随温度的升高而减少,而诱生势随温度的升高而增大.

The temperature characteristic of the acoustic deformation potential surface polaron in polar crystal, which has a weak coupling with surface phonons and a strong coupling with surface optical phonons was studied by using linear-combination-operator method.Numerical calculation for KI crystal as an example, illustrated that the vibration frequency λ and effective mass m^*₂ of the acoustic deformation potential surface polaron decrease with increasing temperature, but the induced potential V^a_i of the acoustic deformation potential surface polaron will increase with increasing temperature.
