Abstract
Polaron binding energy and effective mass are calculated in the fractional-dimensional space approach using the second-order perturbation theory. The effect of carrier density on the static screening correction of the electron-phonon interaction is calculated using the Hubbard's local field factor. It is found that the effective mass and the binding energy both decrease with increase in doping.
