Bismuthene Under Cover: Graphene Intercalation of a Large Gap Quantum Spin Hall Insulator

Advanced Materials, EarlyView.
Bismuthene, a quantum spin Hall insulator with a massive 800 meV topological gap, holds great potential for room‐temperature devices but rapidly degrades in air. This study demonstrates that intercalating bismuthene between SiC and a graphene sheet preserves its structure and topology while preventing oxidation, enabling ex‐situ experiments and ...

Fermi surface transformation at the pseudogap critical point of a cuprate superconductor

Nature Physics, 2020
The nature of the pseudogap phase remains a major puzzle in our understanding of cuprate high-temperature superconductivity. Whether or not this metallic phase is defined by any of the reported broken symmetries, the topology of its Fermi surface remains

The Fermi surface of

Journal of Physics: Condensed Matter, 1996
The de Haas - van Alphen spectrum of is calculated and compared with the experimental spectrum for continuously varying directions of the magnetic field. The local density approximation to spin-density functional theory is used for the self-consistent calculations treating the U 5f electrons as itinerant and including spin - orbit coupling.

Surface Fermi Surfaces [PDF]

Physica Scripta, 1990
Recent work using high resolution angle-resolved photoemission to determine the Fermi surfaces for surface-localized electronic levels on several metal surfaces is reviewed. We examine our fundamental motivation for these studies and their relation to phenomena observed in other branches of chemistry and physics.
