Abstract

We present calculated longitudinal frequency and wavevector dependent dielectric functions of zincblende and wurtzite structure GaN using band energies and wavefunctions generated in the framework of the empirical pseudopotential method. We discuss the anisotropy of the static dielectric function and find that our results are in satisfactory agreement with experimental data for |q| ₒ 0.
