Nature of the metallic and in-gap states in Ni-doped SrTiO${}_3$

Fatima Alarab, Karol Hricovini, Berengar Leikert +6

Epitaxial thin films of SrTiO${}_3$(100) doped with 6% and 12% Ni are studied with resonant angle-resolved photoelectron spectroscopy (ARPES) at the Ti and Ni L2,3-edges. We find tha…
