Zero-point renormalization of the band gap of semiconductors and insulators using the projector augmented wave method

Electron-phonon physics has become an integral part of today's materials science world. In this work, the authors present a00exb i00exn00exi00ext00exi00exo results for the zero-point renormalization of the band gap of various semiconductors and insulators. They use a new implementation of the VASP code that utilizes the sophisticated projector augmented wave method to calculate the electron-phonon perturbation. Two complementary ways of treating the all-electron information are discussed in this context.
