[QE-users] Adsorbate: k-points and smearing

Same smearing, gamma sampling. This should be identical to same smearing and same kpoint mesh. Check also no smearing - it’s there for the metal states, but in case your adsorbate has several levels around the homo or lumo would be safer to keep the smearing.

Should I use the same k-point mesh and smearing for the adsorbate as for the slab calculations (bare metal surface and metal+adsorbate)? Or rather just gamma point and no smearing because it is the only sensible choice for a closed-shell molecule?
