In-situ strain-tuning of the metal-insulator-transition of Ca${}_2$RuO${}_4$ in angle-resolved photoemission experiments

S. Riccò, M. Kim, A. Tamai +12

We report the evolution of the $k$-space electronic structure of lightly doped bulk Ca${}_2$RuO${}_4$ with uniaxial strain. Using ultrathin plate-like crystals, we achieve strain l…
