Spin- and Angle-resolved Photoelectron Spectroscopy Study of the Quantum Spin Hall Insulator Bismuthene and its Precursor Phase
Niclas Tilgner, Andres David Peña Unigarro, Susanne Wolff +6
Recent studies have revealed that a confined bismuth layer at the graphene/SiC interface can be reversibly switched between a topologically trivial precursor phase and the quantum…
Disentangling bulk and surface states in the electronic structure of PtBi(0001)
Stefanie Suzanne Brinkman, Xin Liang Tan, Anders Christian Mathisen +13
The paper studies the electronic structure of PtBi2 (0001) surfaces, using ARPES and calculations to separate bulk bands from surface states on two surface terminations.
Solving the Phase Problem of Diffraction: X-ray Standing Waves Imaging on Bismuthene/SiC(0001)
Niclas Tilgner, Susanne Wolff, Serguei Soubatch +6
The phase retrieval problem is a fundamental shortcoming of all diffraction-based methods, arising from the inability to measure the phase of scattered waves. The (normal incidence…
Reversible Switching of the Environment-Protected Quantum Spin Hall Insulator Bismuthene at the Graphene/SiC Interface
Niclas Tilgner, Susanne Wolff, Serguei Soubatch +8
Quantum Spin Hall Insulators (QSHI) have been extensively studied both theoretically and experimentally because they exhibit robust helical edge states driven by spin-orbit couplin…
