Abstract
We present detailed energy dispersions near the Fermi level on the monolayer perovskite ruthenate , determined by high-resolution angle-resolved photoemission spectroscopy. An orbital selectivity of the kink in the dispersion of has been found: A kink for the Ru orbital is clearly observed, but not for the Ru and ones. The result provides insight into the origin of the kink.
