Charge transfer effects in X-ray core level photoemission from layered transition metal intercalates

Abstract

The authors report X-ray photoemission measurements of core level shifts in TaS2, Fe13/TaS2, Mn14/TaS2 and Ni13/TaS2. The shifts are related to charge transfer from the intercalate 3d ions to the host band structure, and have implications concerning observations of charge density wave amplitudes.
