Band Gap of Atomically Precise Graphene Nanoribbons as a Function of Ribbon Length and Termination
Leopold Talirz, Hajo Söde, Shigeki Kawai +7
We study the band gap of finite armchair graphene nanoribbons (7-AGNRs) on Au(111) through scanning tunneling microscopy/spectroscopy combined with density functional theor…
Majorana Fermions in Magnetic Chains
Rémy Pawlak, Silas Hoffman, Jelena Klinovaja +2
Majorana fermions have recently garnered a great attention outside the field of particle physics, in condensed matter physics. In contrast to their particle physics counterparts, M…
Joule meets van der Waals: Mechanical dissipation via image potential states on a topological insulator surface
Dilek Yildiz, Marcin Kisiel, Urs Gysin +2
Dissipation mechanisms are experimentally studied on topological insulator surfaces of Bi2Te3, where common Joule dissipation was observed to be suppressed due to topologically pro…
Characterization of Hydrogen Plasma Defined Graphene Edges
Mirko K. Rehmann, Yemliha B. Kalyoncu, Marcin Kisiel +8
We investigate the quality of hydrogen plasma defined graphene edges by Raman spectroscopy, atomic resolution AFM and low temperature electronic transport measurements. The exposur…
Mechanical dissipation from charge and spin transitions in oxygen deficient SrTiO_3
Marcin Kisiel, Oleg O. Brovko, Dilek Yildiz +4
Bodies in relative motion separated by a gap of a few nanometers can experience a tiny friction force. This non-contact dissipation can have various origins and can be successfully…
Transoid-to-Cisoid Conformation Changes of Single Molecules on Surfaces Triggered by Metal Coordination
Sara Freund, Rémy Pawlak, Lucas Moser +7
Conformational isomers are stereoisomers that can interconvert over low potential barriers by rotation around a single bond. However, such bond rotation is hampered by geometrical…
