Enhancing single-parameter quantum charge pumping in carbon-based devices
L. E. F. Foa Torres, H. L. Calvo, C. G. Rocha +1
We present a theoretical study of quantum charge pumping with a single ac gate applied to graphene nanoribbons and carbon nanotubes operating with low resistance contacts. By combi…
Graphene: Piecing it together
Mark H. Rümmeli, Claudia G. Rocha, Frank Ortmann +11
Graphene has a multitude of striking properties that make it an exceedingly attractive material for various applications, many of which will emerge over the next decade. However, o…
Mechanically-Induced Transport Switching Effect in Graphene-based Nanojunctions
T. Kawai, M. Poetschke, Y. Miyamoto +3
We report a theoretical study suggesting a novel type of electronic switching effect, driven by the geometrical reconstruction of nanoscale graphene-based junctions. We considered…
