Tunable Colloidal Synthesis Enabling μ-ARPES on Individual Two-dimensional Bismuth Nanocrystals
Fagui He, Yan Yan Grisan Qiu, Simone Mearini +4
Two-dimensional bismuth (Bi) is a promising platform for quantum and energy technologies due to strong spin-orbit coupling, high thermoelectric efficiency, and magnetoresistance. H…
Circular dichroism in the photoelectron angular distribution of achiral molecules
Christian S. Kern, Xiaosheng Yang, Giovanni Zamborlini +9
Circular dichroism in the angular distribution (CDAD) is the effect that the angular intensity distribution of photoemitted electrons depends on the handedness of the incident circ…
Scattering makes a difference in circular dichroic angle-resolved photoemission
Honey Boban, Mohammed Qahosh, Xiao Hou +16
Recent years have witnessed a steady progress towards blending 2D quantum materials into technology, with future applications often rooted in the electronic structure. Since crossi…
Identifying band structure changes of FePS3 across the antiferromagnetic phase transition
Benjamin Pestka, Jeff Strasdas, Gustav Bihlmayer +16
Magnetic 2D materials enable novel tuning options of magnetism. As an example, the van der Waals material FePS3, a zigzag-type intralayer antiferromagnet, exhibits very strong magn…
Giant Rashba-Splitting of One-Dimensional Metallic States in Bi Dimer Lines on InAs(100)
Polina M. Sheverdyaeva, Gustav Bihlmayer, Silvio Modesti +12
Bismuth produces different types of ordered superstructures on the InAs(100) surface, depending on the growth procedure and coverage. The (2x1) phase forms at completion of a Bi mo…
Metalloporphyrins on Oxygen-Passivated Iron: Conformation and Order Beyond the First Layer
David Maximilian Janas, Andreas Windischbacher, Mira Sophie Arndt +15
On-surface metal porphyrins can undergo electronic and conformational changes that play a crucial role in determining the chemical reactivity of the molecular layer. Therefore, und…
Twist angle dependent interlayer transfer of valley polarization from excitons to free charge carriers in WSe/MoSe heterobilayers
Frank Volmer, Manfred Ersfeld, Paulo E. Faria Junior +13
We identify an optical excitation mechanism that transfers a valley polarization from photo-excited electron-hole pairs to free charge carriers in twisted WSe/MoSe heterobi…
Electronic band structure changes across the antiferromagnetic phase transition of exfoliated MnPS probed by -ARPES
Jeff Strasdas, Benjamin Pestka, Milosz Rybak +17
Exfoliated magnetic 2D materials enable versatile tuning of magnetization, e.g., by gating or providing proximity-induced exchange interaction. However, their electronic band struc…
Link between Weyl-fermion chirality and spin texture
Kenta Hagiwara, Philipp Rüßmann, Xin Liang Tan +9
Topological semimetals have recently attracted great attention due to prospective applications governed by their peculiar Fermi surfaces. Weyl semimetals host chiral fermions that…
Molecular anchoring stabilizes low valence Ni(I)TPP on copper against thermally induced chemical changes
Henning Maximilian Sturmeit, Iulia Cojocariu, Matteo Jugovac +14
Many applications of molecular layers deposited on metal surfaces, ranging from single-atom catalysis to on-surface magnetochemistry and biosensing, rely on the use of thermal cycl…
Evaluation of molecular orbital symmetry via oxygen-induced charge transfer quenching at a metal-organic interface
