GENERALIZATION OF FRÖHLICH'S OPERATOR FOR THE ELECTRON-PHONON COUPLING IN POLAR CRYSTALS

U. Schröder , M. Weiss , R. Reiger , J. Page

A formalism is developed for the coupling of excess electrons to phonons in polar crystals whose lattice dynamics are describable in terms of a shell model. Phonon dispersion and coupling to other than the usual [MATH] = O,L0 phonons are included. Numerical results for polarons in III-V and II-VI compounds are reported.
