The Fröhlich electron–phonon interaction in a multiple quantum well structure (MQW) is studied in a perturbation scheme. The dispersion relation of the polaron is obtained with an analytic form factor in a well and an overlap factor between wells. The polaronic binding energy and effective mass are compared with results for a single quantum well.
