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…
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…
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…
CDW slips and giant frictional dissipation peaks at the NbSe surface
Markus Langer, Marcin Kisiel, Rémy Pawlak +8
Accessing, controlling and understanding nanoscale friction and dissipation is a crucial issue in nanotechnology, where moving elements are central. Recently, ultra-sensitive nonco…
Superlubricity of Graphene Nanoribbons on Gold Surfaces
Shigeki Kawai, Andrea Benassi, Enrico Gnecco +9
The state of vanishing friction known as superlubricity has important applications for energy saving and increasing the lifetime of devices. Superlubricity detected with atomic for…
