Studies of Optical and Phonon Properties of Wurtzite Gallium Nitride: First-principle Calculations
Using the plane-wave pseudopotential approach inside density functional theory, we investigated the optical properties of wurtzite (WZ) GaN semiconductor such as refractive index n(), absorption coefficient (), and dielectric constant (DFT). The optical phonon modes were also estimated at 0 GPa using the Cambridge Serial Total Energy Package (CASTEP) software’s phonon computation. The computed values…
