We have evaluated the effect of confinement in a thin stab on the polaron energy and effective mass. The result is obtained for an arbitrary temperature and evaluated numerically at zero temperature. We estimate that the change in the polaron effective mass due to its interaction with-the lattice is reduced by 60% of its infinite crystal value when the slab thickness is equal to the polaron radius.
