[Smeagol-discuss] Fermi level

[Ivan Rungger]

Hello Kamaram,

  I am not sure I understand the question, but here is how the Fermi
energy is set in smeagol. The main assumption is that at the boundaries
of the scattering region the Hartree potential is identical to the one
of the bulk  leads calculation. Therefore during the selfconsistency for
the scattering region the planar average of the potential at the
boundaries is always set equal to that of the bulk (via the hartreeleads
options). In this way by construction the leads and the scattering
region have the have same Fermi energy.

Cheers,

 Ivan
