摘要:

We applied X-ray Absorption Spectroscopy, in combination with electronic band structure calculations, to probe the electronic structure before and after lithium intercalation into TiS2, TiSe2and 2H-NbSe2. We are then able to precisely determine the nature of the charge transfer from intercalated lithium to the host It is shown that lithium is not fully ionized and that chalcogen atoms are deeply involved in the charge transfer process.
