Yuriy Kudriavtsev

Covalent radius equals to half of the covalent bond length. It looks a quite reasonable value to estimate atomic well in the same material (with covalent bond) if a surface reconstruction can be neglected. I have no idea about Se: if there is a reconstruction for it or no.

Loveleen K Brar

do you mean potential well depth or as @Yuriy Kudriavtsev and @Md. Arifur Rahman mentioned the surface depth?
