| Abstract: | In this paper, the dispersion of the longitudinal optical phonon is considered in a parabolic approxiamation. The ground state energy, effective mass and polarization potential are calculated. Itis found that the more the phonon dispersion, the larger are the self-trapped energy and effective mass of a polaron, and the smaller is the screening radius. |
