Dear All

In the attached figure, which is a doped SnTe system, the Fermi level (Ef=10.123 eV) is found to cross the conduction band at the gamma point. It actually overlap with the highest occupied level at R point. The lowest unoccupied level (L.U. Level) is towards A of the gamma point. For me, the energy level (red bold broken curve) between the Ef and the L.U. Level is unusual. Throughout the different paths that I tried (including M-gamma-Z) it is found between Ef and the L.U. Level. Both the highest occupied level and the lowest unoccupied level are found on it. What can I say about it? at least, is it part of the conduction band or of the valence band?

Thank you in advance
