Projected augmented wave potentials
WebMar 19, 2024 · Projected augmented wave (PAW) potentials [ 27] and plane wave basis sets (cut-off of 500 eV) were used. The exchange correlation term was modelled using the generalized gradient approximation (GGA) as parameterized by Perdew, Burke, and Ernzerhof (PBE) [ 28 ]. All structures were optimized using the conjugate gradient … WebNov 11, 2024 · The electron–ionic core interaction is represented by the projected augmented wave (PAW) potentials [ 26 ]. Perdew-Burke-Ernzerhof (PBE) [ 27] form within the GGA was selected to treat the electron exchange and correlation, which yields the correct ground state structure of the combined systems.
