摘要：

We present detailed energy dispersions near the Fermi level on the monolayer perovskite ruthenate Sr2RuO4, determined by high-resolution angle-resolved photoemission spectroscopy. An orbital selectivity of the kink in the dispersion of Sr2RuO4 has been found: A kink for the Ru 4d(xy) orbital is clearly observed, but not for the Ru 4d(yz) and 4d(zx) ones. The result provides insight into the origin of the kink.
