The two-dimensional (2D) metal PtCoO$_2$ 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 theoretically predict a strong intrinsic spin Hall effect. This originates from six strongly-tilted Dirac cones that we find in the electronic structure near the Fermi surface, where a gap is opened by large spin-orbit coupling (SOC). This is underpinned by rich topological properties; in particular, the… Expand

Nearly free electrons in a 5d delafossite oxide metal
Transport and ARPES reveal extremely good metallicity arising from almost free-electron behavior in single-crystal PtCoO2, establishing Pt coO2 as a model nearly-free–electron system in a 5d delafossite transition-metal oxide. Expand
Hidden kagome-lattice picture and origin of high conductivity in delafossite PtCoO2
We study the electronic structure of delafossite PtCoO$_2$ to elucidate its extremely small resistivity and high mobility. The band exhibits steep dispersion near the Fermi level despite the factExpand

We study the electronic surface states of the semiconducting alloy bismuth antimony Bi1�xSbx. Using a phenomenological tight-binding model, we show that the Fermi surface for the 111 surface statesExpand
Topological quantum chemistry
A complete electronic band theory is proposed, which builds on the conventional band theory of electrons, highlighting the link between the topology and local chemical bonding and can be used to predict many more topological insulators. Expand
Intrinsic spin Hall effect in platinum: first-principles calculations.
It is argued that the large SHE observed experimentally in platinum is of intrinsic nature and that the vertex correction due to impurity scattering vanishes. Expand

On the metallic conductivity of the delafossites PdCoO2 and PtCoO2
The origin of the quasi two-dimensional behavior of PdCoO2 and PtCoO2 is investigated by means of electronic structure calculations. They are performed using density functional theory in theExpand
Topological insulators with inversion symmetry
Topological insulators are materials with a bulk excitation gap generated by the spin-orbit interaction that are different from conventional insulators. This distinction is characterized by ${Z}_{2}$Expand
Maximal Rashba-like spin splitting via kinetic-energy-coupled inversion-symmetry breaking
The findings therefore provide opportunities for creating spin-textured states and suggest routes to interfacial control of inversion-symmetry breaking in designer heterostructures of oxides and other material classes. Expand
