Thank you Darwin123 ! A good lesson I learned here: The eigenvectors from tight-binding calculation is as important as eigen-energies ! The latter gives the band structure, while the eigenvectors tell one the orbital composition.

Hi, Does anyone have an intuitive idea of why it is always the valence bands split under spin/orbit coupling, but not conduction band? (or a much smaller splitting than valence band) I know through tight-binding calculations, if I plug in numbers correctly, conduction bands always have...
