A new decoupling approximation has been introduced in the Green's function equation-of-motion analysis of the large polaron. Considering those Feynman diagrams which correspond to the two-phonon Tamm-Dancoff approximations an expression for the polaron ground state energy has been derived. It is fou

The ground state energy of a polaron in a superlattice was calculated using the double-time Green functions. The effective mass of the polaron along the planes perpendicular to the superlattice axis was also calculated. The dependence of the ground state energy and the effective mass along the plane
