• In this paper, the temperature dependence of the properties of polaron, which is weakly coupled with bulk LO phonons and strongly coupled with SO phonons, in a slab of polar crystal is studied by means of a modified second LLP transformation for the first time. An expressions for the self-trapping energy and the effective mass of the polaron in a slab of polar crystal as a function of the temperature and slab thickness are derived by using a linear combination operator and two modified LLP variational method. Our numerical results of the self-trapping energy and the effective mass for KCl show that the polaron self-trapping energy and effective mass in a polar crystal are strongly related to the slab thickness and the temperature. The self-trapping energy and the effective mass will decrease with increasing slab thickness and temperature.
