摘要: Abstract We present calculated results for the wavevector and frequency dependent dielectric functions of zincblende wurtzite GaN based on empirical pseudopotential band structures. The q → -dependent static functions, ϵ∞( ), are found to be similar two crystal modifications. optical ϵ∞(ω), however, different in range 6 eV
