[Pw_forum] Which part is the main potential for obtaining the work function?

[Weiguang Chen]

Hi,

We know the potential of a solid state consists of V_bare(atomic core),
V_hartree(Hartree contribution) and V_xc(exchange correalation) and so on. I
want to know which component is the main source when we try to get the work
function.

Thanks
