Webb21 apr. 2024 · The energies were determined with conventional DFT and the dispersion-corrected DFT-D3 method , both of which use the Perdew-Burke-Ernzerhof (PBE) exchange-correlation functional. Details of the DFT calculations can be found in the supplementary materials along with CH 4 adsorption energies obtained by using several … WebbTo simulate SLs under applied strain, we keep the cell volume fixed and relax the cell shape in cross-plane [001] direction. We perform the electronic structure calculations with DFT using the generalized gradient approximation (GGA) implemented in the VASP with the Perdew-Burke-Ernzenhof (PBE) exchange-correlation functional [61].
