| Abstract: | Considering both the electron interaction with the bulk longitudinal optical (LO) phonon and tronelecthe interaction with the surface optical (SO) phonon, we obtained the slab thickness dependence of the effective potentials and the binding energy of the bound polaron confined in a slab of polar crystal by using perturbative variational method. We also discussed the physical meaning of the variational parameter changed with the impurity position. |
