We have performed calculations of the electron-phonon scattering rate of zinc blende GaN using the rigid psuedo-ion model. We find that the calculated rates are relatively insensitive to assumptions made regarding the underlying band structure and phonon dispersion and, to a very good approximation, follow the electronic density of states. The latter result allows an optical deformation scattering constant to be fitted.
