Surface chemistry investigation of an additively manufactured Al-Mg-Si-Zr alloy: Studies from experiments and first-principles simulation
Zhengqing Wei, Philip Grimm, Inna Plyushchay +5
The surface chemistry of additively manufactured aluminum alloys plays a critical role in corrosion resistance and joining with external materials. In this work, the near-surface e…
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…
Quantum confinement in semiconductor random alloys: a case study on Si/SiGe/Si
Daniel Dick, Florian Fuchs, Sibylle Gemming +1
Local composition fluctuations in random alloys become crucial when one or more dimensions are reduced to the nanoscale. Using extended Hückel theory, we study the semiconductor ra…
Graphene-capped bismuthene on SiC as a platform for correlated quantum spin Hall edge states
Huu Thoai Ngo, Zamin Mamiyev, Niclas Tilgner +4
Epitaxial bismuthene on SiC(0001) hosts symmetry-protected metallic edge states within a large bulk band gap, establishing it as a promising two-dimensional topological insulator f…
