MxTiSe2 (M=Cr, Mn, Cu) electronic structure study by methods of resonance X-ray photoemission spectroscopy and X-ray absorption spectroscopy
چکیده انگلیسی

Intercalation of Cu and Mn between the layers of TiSe2 leads to the charge transfer from the doped atom to Ti atoms, electronic states of which form the conduction band of TiSe2. This situation drastically differs from another one being observed during intercalation of other transition metals into TiSe2 that leads to the formation of covalent complexes consisting of intercalated atom and nearest neighborhood of the host lattice. Substitution of Ti by Cr in the host lattice positions does not show both charge transfer nor formation of covalent complexes.


► The formation of the electronic structure in MxTiS2 is studied.
► Increasing amount of CrSe2 in CrxTi1−xSe2 together with Cr content is observed.
► The intercalation of Cu state of Cu atoms is close to a state of free ions.
► In MnxTiSe2 the charge transfer from the Mn atoms in the 3d band of Ti is observed.
