Vr. Galakhov et al., ELECTRONIC-STRUCTURE OF LINIO2, LIFEO2 AND LICRO2 - X-RAY PHOTOELECTRON AND X-RAY-EMISSION STUDY, Solid state communications, 95(6), 1995, pp. 347-351
We present X-ray photoelectron (XPS) and soft X-ray emission (XES) spe
ctra of LiNiO2, LiFeO2 and LiCrO2. The concentration of holes per oxyg
en ion in LiNiO2 is estimated and a classification of the investigated
oxides is given. We propose, that LiFeO2 should be placed in the inte
rmediate region between a charge-transfer and a Mott-Hubbard insulator
and LiCrO2 can most likely be assigned to the Mott-Hubbard insulators
.
