What is the artifact of the Pt valence density referred to in example04 of the Environ module?
I saw your post on the google group. I guess you haven’t gotten a response there yet. So the problem stems from the fact that pseudopotentials don’t have core electrons. If you were to compute the ...

VASP - suggestion on optimization of interfaced slabs
Thanks to @ShaunHa's reply, which cleverly allows slabs to be stacked in the z-direction, I created a customised (simplified) add_adsorbate function that can stack slabs in the 'x', 'y' or 'z' ...

What is the meaning of a "free energy per unit surface area" vs "pressure" plot?
The graph does show that at high pressures the $\Delta G$ per surface area values are lower, which would usually indicate stability. I agree with you that as the pressure goes lower, the stability ...
