I am wondering which ISMEAR value I should choose for a system consisting of defected graphene (monovacancy) and Fe nanoparticles. According to the VASP manual, for relaxations in …
WebAug 12, 2010 · According to the VASP manual, for relaxations in metals always use ISMEAR=1 or ISMEAR=2 and an appropriate SIGMA value. Also, for semiconductors like graphene, it says avoide ISMEAR > 0. I am looking into O2 and CO dissociation on the Fe particles adsorbed on the defected graphene. In this case, I am wondering if I should … WebDec 22, 2024 · It has the potential to influence the (extrapolated, 0 K) energy, although the differences are likely to be minor. They probably just forgot to include the flags in the input file for that final calculation, but I'd recommend keeping them for consistency. The defaults are ISMEAR=1 and SIGMA=0.2, which is quite different.
