Abstract
With the Lee-Low-Pines intermediate coupling method, a polaron very ne ar a polar semiconductive heterointerface is discussed by considering the influence of both branches of the interface optical phonon modes. The ground state energy and the normalized effective mass of the polar on are calculated. It is shown that one of the two branches of the pho non modes is the more important, but the contribution of the other bra nch to the polaron is not negligible.
