[Wien] "Plane average potential" for surface

[Salman Zarrini]

Dear Wien2k User,

The work function could be clearly calculated via (E(vac)-E(F)) where  
E(vac) is the coulomb potential either at Z=0 or Z=0.5 of a  
slab-vacuum unit cell, however, I was wondering if it is possible to  
have coulomb potential in the different Z of the unitcell aslo?  
Actually, I would like to plot "Plane average potential" respect to Z  
for a slab-vacuum model. So, any suggestions would be appreciated in  
advance.

Cheers,

Salman Zarrini
