Nature of the metallic and in-gap states in Ni-doped SrTiO3

Nature of the metallic and in-gap states in Ni-doped SrTiO3

Epitaxial thin films of SrTiO3(100) doped with 6% and 12% Ni are studied with resonant angle-resolved photoelectron spectroscopy at the Ti and Ni L2,3-edges. We find that the Ni doping shifts the valence band of n-doped pristine SrTiO3 toward the Fermi level (in the direction of p-doping) and reduci...
