Ambipolar doping-induced surface in-gap state on Mott-insulating Ca $_{2}$ RuO $_{4}$

M. Horio, T. Wada, V. Granata +4

We report an x-ray photoemission spectroscopy study of Ca $_{2}$ RuO $_{4}$ surface-dosed with Cs alkali atoms and C $_{60}$ molecules. Due to its small ionization energy (large electron a…

Evidence of electronic states driving current-induced insulator-to-metal transition

V. K. Bhartiya, R. Hartmann, F. Forte +16

On demand current-driven insulator-to-metal transition (IMT) is pivotal for the next generation of energy-efficient and scalable microelectronics. IMT is a key phenomenon observed…

Hallmarks of Hund's coupling in the Mott insulator Ca $_{2}$ RuO $_{4}$

D. Sutter, C. G. Fatuzzo, S. Moser +22

A paradigmatic case of multi-band Mott physics including spin-orbit and Hund's coupling is realised in Ca $_{2}$ RuO $_{4}$ . Progress in understanding the nature of this Mott insulating p…
