Tuning Anti-Klein to Klein Tunneling in Bilayer Graphene
Renjun Du,Ming-Hao Liu,Ming-Hao Liu,Jens Mohrmann,F. Wu,F. Wu,Ralph Krupke,Ralph Krupke,Hilbert von Löhneysen,Klaus Richter,Romain Danneau +10 more
TL;DR: In gapped bilayer graphene, quasiparticle tunneling and the corresponding Berry phase can be controlled such that they exhibit features of single-layer graphene such as Klein tunneling, and a transition from anti-Klein tunneling to nearly perfect Klein Tunneling is demonstrated.

High critical-current superconductor-InAs nanowire-superconductor junctions
TL;DR: The fabrication of InAs nanowires coupled to superconducting leads with high critical current and widely tunable conductance and a double lift-off nanofabrication method to get very short nanowire devices with Ohmic contacts are reported.
Tailoring supercurrent confinement in graphene bilayer weak links
Rainer Kraft,Jens Mohrmann,Renjun Du,Pranauv Balaji Selvasundaram,Muhammad Irfan,Muhammad Irfan,Umut Nefta Kanilmaz,F. Wu,F. Wu,Detlef Beckmann,Hilbert von Löhneysen,Ralph Krupke,Anton R. Akhmerov,Igor V. Gornyi,Romain Danneau +14 more
TL;DR: In this article, the authors used local gates to control confinement, amplitude and density profile of the supercurrent induced in one-dimensional nanoscale constrictions, defined in bilayer graphene-hexagonal boron nitride van der Waals heterostructures.
Highly sensitive and broadband carbon nanotube radio-frequency single-electron transistor
TL;DR: In this paper, the authors investigated radio-frequency single-electron transistor operation of single-walled carbon nanotube quantum dots in the strong tunneling regime, and they obtained a gain-bandwidth product of 3.7×1013
