Projected augmented wave paw potentials
WebThe projected augmented wave (PAW) pseudopotentials with valence-electron configurations of 1s 1, 2s 2 2p 2, 2s 2 2p 3, 2s 2 2p 4, and 4s 1 3d 8 were employed for H, C, N, O, and Co, respectively. The exchange-correlation interaction was described by generalized gradient approximation (GGA) with the revised Perdew–Burke–Ernzerhof … WebThe projected augmented wave (PAW) potentials[4,5] was chosen to describe the ionic cores and take valence electrons into account using a plane wave basis set with a kinetic energy cutoff of 400 eV. The correction function Grimme is used to correct the van der Waals force (vdW) dispersion interaction.[6]
