Correlated electron metal properties of the honeycomb ruthenate NaRuO
L. S. I. Veiga, M. Etter, E. Cappelli +7
We report the synthesis and characterisation of polycrystalline NaRuO, a layered material in which the Ru ( configuration) form a honeycomb lattice. The optima…
Direct evidence for flat bands in twisted bilayer graphene from nano-ARPES
Simone Lisi, Xiaobo Lu, Tjerk Benschop +21
Transport experiments in twisted bilayer graphene revealed multiple superconducting domes separated by correlated insulating states. These properties are generally associated with…
A laser-ARPES study of LaNiO3 thin films grown by sputter deposition
Edoardo Cappelli, Willem Tromp, Siobhan McKeown Walker +4
Thin films of the correlated transition-metal oxide LaNiO undergo a metal-insulator transition when their thickness is reduced to a few unit cells. Here, we use angle-resolved…
High-resolution photoemission on Sr2RuO4 reveals correlation-enhanced effective spin-orbit coupling and dominantly local self-energies
A. Tamai, M. Zingl, E. Rozbicki +17
We explore the interplay of electron-electron correlations and spin-orbit coupling in the model Fermi liquid Sr2RuO4 using laser-based angle-resolved photoemission spectroscopy. Ou…
In-situ strain-tuning of the metal-insulator-transition of CaRuO in angle-resolved photoemission experiments
S. Riccò, M. Kim, A. Tamai +12
We report the evolution of the -space electronic structure of lightly doped bulk CaRuO with uniaxial strain. Using ultrathin plate-like crystals, we achieve strain l…
