摘要： 随着固体科学和技术的发展,晶体表面和界面极化子的性质,一直受到人们的重视[1,2].近年来,已有不少作者[3,4]研究了表面和界面极化子,其中很多工作集中于弱,中耦合的情形.

Abstract: In this paper, the effective Hamiltonian of the strong-coupling surface polaron in polar crystals at finite temperature is derived by means of the linearcombination operators proposed by Huybrechts. The numerical results for KBr are given. It is shown that the lattice vibration weakens the electron-pbonon coupling, and the thickness of the ‘dead layer’ of the polaron increases with the increase of temperature.
