Dear Siesta users: Recently I was using siesta to simulating CO adsorption on Ge(100) surface, so I need a Germanium pseudopotential. Considering CO anti-Pi orbital may accept electron from Ge fulfilled 3d orbitals, I need to treat the 3d orbital of Ge as valence ones. I read the manual of atom, it seems to only treat the whole 4s, 4p 4d as valence ones, but not 3d. Can anyone give me some suggestions and how-to? Your help will be greatly appreciated.
