electron-electron interaction in doped graphene

[jai]

Hell everyone,

How to investigate electron-electron interactions in Pd doped graphene sheet?

[zh]

In the DFT calculation, the electron-electron interaction is already included.

Dear Sir,
        Is it only included in DFT ?? in case of the tight binding type methods (slater koster, Huckel), is it not provided??

Please read the background of the ATK-SE in the manual: http://quantumwise.com/documents/manuals/latest/ReferenceManual/index.html/chap.atkse.html.

One of the important components of electron-electron interaction is the Hartree potential. The electron-electron interaction is not included in the non-self-consistent tight-binding model, however, it is included in the self-consistent tight-binding model.
