[Pw_forum] Net Surface dipole

[ulrich.aschauer at dcb.unibe.ch]

Dear Elliot,

If I understand your question correctly, then plot_num=11 (electrostatic potential) with pp.x should give you that information. If you do a 1D plot along the surface normal and the potential does not become flat in the vacuum region, then there is a net dipole.

Best regards,
-uli

Dear All,
How does one know or can one tell from the content of the output file of
a full geometry optimization calculation (relax) that there's a net
surface dipole density in an asymmetric system for adsorption studies.
For eg. CO adsorbed on only one side of a nickel slab.

Thank you.

Kind Regards,
Elliot.
