Abstract
A theory of quasi-two-dimensional (2D) polarons in semiconductor quantum wells is presented. We have derived analytical expressions for the energy-gap shift and effective polaron mass in the small-well-width limit. The analytical results agree exactly with those obtained for an ideal 2D system in the limit of zero well width. For larger quantum-well widths, we have numerically evaluated the values for the energy-gap shift and effective mass of a polaron.
