Hidden kagome-lattice picture and origin of high conductivity in delafossite PtCoO
Hidetomo Usui, Masayuki Ochi, Sota Kitamura +8
We study the electronic structure of delafossite PtCoO to elucidate its extremely small resistivity and high mobility. The band exhibits steep dispersion near the Fermi level d…
Dual quantum confinement and anisotropic spin splitting in the multi-valley semimetal PtSe
O. J. Clark, F. Mazzola, J. Feng +6
We investigate the electronic structure of a two-dimensional electron gas created at the surface of the multi-valley semimetal 1T-PtSe. Using angle-resolved photoemission and f…
Spin Hall effect in 2D metallic delafossite PtCoO and vicinity topology
Sota Kitamura, Hidetomo Usui, Robert-Jan Slager +9
The two-dimensional (2D) metal PtCoO is renowned for the lowest room temperature resistivity among all oxides, close to that of the top two materials Ag and Cu. In addition, we…
Probing spin correlations using angle resolved photoemission in a coupled metallic/Mott insulator system
V. Sunko, F. Mazzola, S. Kitamura +16
A nearly free electron metal and a Mott insulating state can be thought of as opposite ends of possibilities for the motion of electrons in a solid. In the magnetic oxide metal PdC…
Orbital- and -selective hybridisation of Se 4p and Ti 3d states in the charge density wave phase of TiSe
Matthew D. Watson, Oliver J. Clark, Federico Mazzola +5
We revisit the enduring problem of the charge density wave (CDW) order in TiSe, utilising photon energy-dependent angle-resolved photoemission spectroscop…
Unconventional magneto-transport in ultrapure PdCoO2 and PtCoO2
Nabhanila Nandi, Thomas Scaffidi, Pallavi Kushwaha +11
We have studied magneto transport in the single-band, quasi-two-dimensional metals PdCoO2 and PtCoO2, which have extremely long mean free paths. We observer a strong temperature de…
