Zusammenfassung
We present a correction scheme for periodic Γ-only GW calculations in a Gaussian basis. For four benchmark systems, the dependence of the corrected GW quasiparticle levels on the cell size is reduced by a factor of three to ten compared to GW calculations without correction. The correction scheme comes along with negligible computational cost and enables GW calculations for supercells containing hundreds of atoms with Gaussian basis functions.
