[Pw_forum] work function - rrkj pseudopotential

[Mohamad Moadeli]

Dear all,

I am trying to calculate work function for a graphene-metal system. The
problem is that when performing the calculation using the RRKJ
pseupotentials (Cu.pz/pbe-d-rrkjus.UPF
<http://www.quantum-espresso.org/wp-content/uploads/upf_files/Cu.pz-d-rrkjus.UPF>
, Ag.pz/pbe-d-rrkjus.UPF
<http://www.quantum-espresso.org/wp-content/uploads/upf_files/Ag.pz-d-rrkjus.UPF>,
and Au.pz/pbe-d-rrkjus.UPF
<http://www.quantum-espresso.org/wp-content/uploads/upf_files/Au.pz-d-rrkjus.UPF>)
the results of average.x is a peak instead of a well. By changing the
pseudopotential (any other downloaded from QE page), everything goes well.
As we know, if plot_num=11, V_xc is not added to pp.x results. How could it
happen?

Any help will be greatly appreciated.
