Abstract
The method recently developed by Larsen is generalized to treat, in the limit of strong magnetic field, the interface polaron in a semi-infinite polar crystal. Both the bulk longitudinal optical phonon and the surface optical phonon and their interactions with the magnetic field are included. Ground-state energy corrections up to the fourth-order perturbation are expressed as functions of the magnetic field and a parameter characterizing the mean distance of the polaron from the interface.
