Tuning the supercurrent distribution in parallel ballistic graphene Josephson junctions
Philipp Schmidt, Luca Banszerus, Benedikt Frohn +7
We report on a ballistic and fully tunable Josephson junction system consisting of two parallel ribbons of graphene in contact with superconducting MoRe. By electrostatic gating of…
Optomechanical coupling and damping of a carbon nanotube quantum dot
N. Hüttner, S. Blien, P. Steger +3
Carbon nanotubes are excellent nano-electromechanical systems, combining high resonance frequency, low mass, and large zero-point motion. At cryogenic temperatures they display hig…
Minigap and Andreev bound states in ballistic graphene
Luca Banszerus, Florian Libisch, Andrea Ceruti +7
A finite-size normal conductor, proximity-coupled to a superconductor has been predicted to exhibit a so-called minigap, in which quasiparticle excitations are prohibited. Here, we…
Quantum capacitance mediated carbon nanotube optomechanics
Stefan Blien, Patrick Steger, Niklas Hüttner +2
Cavity optomechanics allows the characterization of a vibration mode, its cooling and quantum manipulation using electromagnetic fields. Regarding nanomechanical as well as electro…
Quartz tuning-fork based carbon nanotube transfer into quantum device geometries
S. Blien, P. Steger, A. Albang +2
With the objective of integrating single clean, as-grown carbon nanotubes into complex circuits, we have developed a technique to grow nanotubes directly on commercially available…
Weak localization and Raman study of anisotropically etched graphene antidots
Florian Oberhuber, Stefan Blien, Stefanie Heydrich +6
We study a crystallographic etching process of graphene nanostructures where zigzag edges can be prepared selectively. The process involves heating exfoliated single-layer graphene…
