Abstract:

We synthesize CrxTi1-xSe2 (x= 0-0 83) and CrxTi1-xS2 (x= 0 3-0 4) systems and study the structure of these materials on mono- and polycrystalline samples It appeared that an increase in chromium content leads to inversion of titanium diselenide intercalated with chromium to chromium diselenide intercalated with titanium The XPS of core levels and valence bands of 1T-CrxTi1-xSe2 and CrxTi1-xS2 was also investigated and it was shown that in In-layer and Inter-layer positions the atoms of chromium and titanium are characterized by a slightly differing oxidation state Chromium LDOS model calculations were carried out and the results being in agreement with the experimental data show that the Cr 3d density of electronic states of chromium in Ti-positions in the host lattice displays half-metallic properties while the Cr 3d density of electronic states of intercalated chromium is far from being half-metallic (C) 2010 Elsevier B V All rights reserved
