AC Josephson effect in a gate-tunable CdAs nanowire superconducting weak link
Roy Haller, Melissa Osterwalder, Gergő Fülöp +3
Three-dimensional topological Dirac semimetals have recently gained significant attention, since they possess exotic quantum states. When constructing Josephson junctions utilizing…
Controllable pn junctions in threedimensional Dirac semimetal CdAs nanowires
Janice Ruth Bayogan, Kidong Park, Zhuo Bin Siu +11
We demonstrate a controllable pn junction in a threedimensional Dirac semimetal (DSM) CdAs nanowire with two recessed bottom gates. The device exhibits four different…
Quantum dots formed in three-dimensional Dirac semimetal CdAs nanowires
Minkyung Jung, Kenji Yoshida, Kidong Park +9
We demonstrate quantum dot (QD) formation in three-dimensional Dirac semimetal CdAs nanowires using two electrostatically tuned pn junctions with a gate and magnetic…
GHz nanomechanical resonator in an ultraclean suspended graphene p-n junction
Minkyung Jung, Peter Rickhaus, Simon Zihlmann +3
We demonstrate high-frequency mechanical resonators in ballistic graphene p-n junctions. Fully suspended graphene devices with two bottom gates exhibit ballistic bipolar behavior a…
Measurements of a Quantum Dot with an Impedance-Matching On-Chip LC Resonator at GHz Frequencies
M. -C. Harabula, T. Hasler, G. Fülöp +3
We report the realization of a bonded-bridge on-chip superconducting coil and its use in impedance-matching a highly ohmic quantum dot (QD) to a measurement setup. The…
Microwave Photodetection in an Ultraclean Suspended Bilayer Graphene pn Junction
Minkyung Jung, Peter Rickhaus, Simon Zihlmann +2
We explore the potential of bilayer graphene as a cryogenic microwave photodetector by studying the microwave absorption in fully suspended clean bilayer graphene pn junctions in t…
