| Abstract: | he Low-lying energy levels of the polarons in polar-crystal slab are investigated.The inter-actions of the electron with both the longitudinal-optical(LO)phonon and the surface optical(SO)phonon are included.By using a perturbation theory, the self-energy and the effective massof the polaron as functions of the slab thickness are calculated.The interactions of the virtualphonons and the recoiling electrons are exactly considered in calculation. |

| Keywords: | intermediate-coupling polaron polar-crystal slab virtual phonon |
