Abstract
The polaron binding energy and effective mass are obtained for bulk III-V nitride compounds with wurtzite crystalline structure with the use of a recently derived dielectric continuum Fröhlich-like electron-phonon interaction Hamiltonian which accounts for the mixing of the longitudinal optical and transverse optical polarization due to the anisotropy. Corrections are calculated up to second order in the coupling constants. Numerical results are reported for GaN and AlN. Good quantitative agreement with experimental results for the electronic effective mass is obtained for GaN.
