First-principles calculations of the electronic band structure for the layer-type compounds 2 H− Nb Se 2 and 2 H− Mo S 2 predict a 1-eV hybridization gap within the d z 2 and d xy, d x 2− y 2 manifolds of the metal-atom 4 d bands. This produces a narrow (∼ 1 eV) filled valence band in 2 H− Mo S 2 and a half-filled conduction band in 2 H− Nb Se 2, in agreement with electrical, optical, and recent photoemission date.
