Hi,

Can VASP do calculations on system containing one or more excess electrons, or ions? Something like that on Science, Vol. 309, p914, 2005.

Any help will be greatly appreciated.

yes, you just need to set the number of electrons manually:

Danny,

Thank you very much for the help.

Another question:
Does VASP has electron pseudo-potential, so that we can simulate the interaction of e- with the molecule (at solid surface)?

not to my knowledge: check the PP database you got with the source
