[Pw_forum] Dipole correction in superlattice with no vacuum

[Stefano de Gironcoli]

I think one could use the electric field option putting a dipole layer deep in the bulk of one of the two materials (maybe the metal) and monitor when the macroscopic average of the electrostatic potential is horizontal in the oxide to obtain the electrostatic lineup.
