<p>Look in the user guide for the option to calculate this using lapw0, & you then can use lapw5 although I dont think it is automated.</p>
<p>Note, by definition the vacuum potential is zero, which gives you the absolute value.</p>

Dear Wien2k User,<br>
<br>
The work function could be clearly calculated via (E(vac)-E(F)) where<br>
E(vac) is the coulomb potential either at Z=0 or Z=0.5 of a<br>
slab-vacuum unit cell, however, I was wondering if it is possible to<br>
have coulomb potential in the different Z of the unitcell aslo?<br>
Actually, I would like to plot "Plane average potential" respect to Z<br>
for a slab-vacuum model. So, any suggestions would be appreciated in<br>
advance.<br>
<br>
Cheers,<br>
<br>
