摘要：

Theoretical studies of phonon-dispersion curves and the polar-optical scattering process for 2H PbI2 are presented. A rigid-ion model with anisotropic effective charges is used to calculate the phonon-dispersion curves. The carrier mobility and its anisotropy due to polar-optical scattering as a function of temperature are calculated. Results are in good agreement with the experimental data.
