Abstract
The effective parameter of the electron-phonon interaction in a semiconductor film on ionic substrates has been determined. It is shown that interface phonons “transfer” the polarization of the medium from the substrate to the film. As a result, the polaron binding energy and the effective mass of carriers in the same film on different substrates can vary by tens or even hundreds of percent. Conditions for the realization of strong interaction for various films are found.
