Electronic structure of studied by x-ray photoelectron and x-ray emission spectroscopies

A single crystal has been the subject of a combined investigation by high-resolution x-ray photoelectron spectroscopy (XPS), x-ray emission spectroscopy (XES) with both electron and energy-selective x-ray excitation ( , and emission) and x-ray absorption spectroscopy (XAS) . We performed first-principles tight-binding LMTO band-structure calculations for in both the monoclinic and tetragonal rutile phases and compared the densities of states (DOS) with the experimental data. From this we conclude that the electronic structure of is more bandlike than correlated.
