Hidden Ladder in SrMoO${}_3$/SrTiO${}_3$ Superlattices: Experiments and Theoretical Calculations

Hiroshi Takatsu, Naoya Yamashina, Masayuki Ochi +6

A double-layered perovskite oxide Sr${}_3$Mo${}_2$O${}_7$ is considered a "hidden ladder" system with wide and narrow bands near the Fermi level, for which high-$T_{\mathrm{c}}$ superconducti…
