An X-ray photoelectron and X-ray emission study of the electronic structure of Nb trichalcogenides and their lithium intercalates

An X-ray photoelectron and X-ray emission study of the electronic structure of Nb trichalcogenides and their lithium intercalates

The electronic structure of Nb trichalcogenides and their lithium intercalates was studied using X-ray photoelectron and X-ray emission spectroscopy. It was found that the metal 4d levels mainly contribute to the upper part of the NbSe 3 and NbS 3 valence zones whereas the deeper part of the valence...

Zusammenfassung:The electronic structure of Nb trichalcogenides and their lithium intercalates was studied using X-ray photoelectron and X-ray emission spectroscopy. It was found that the metal 4d levels mainly contribute to the upper part of the NbSe 3 and NbS 3 valence zones whereas the deeper part of the valence zones is filled by the chalcogen levels. The intercalation was found to change the charge state of both Nb and chalcogen atoms.
