Critical Current Scaling in Long Diffusive Graphene-Based Josephson Junctions.
(Nano letters, 2016-08)We present transport measurements on long, diffusive, graphene-based Josephson junctions. Several junctions are made on a single-domain crystal of CVD graphene and feature the same contact width of ∼9 μm but vary in length ... -
Graphene-based Josephson Triode
There has been a growing interest to the materials with broken time-reversal and inversion symmetry, which can support non-reciprocal superconducting currents [1]. This search for an intrinsic superconducting diode has so ... -
Importance of diameter control on selective synthesis of semiconducting single-walled carbon nanotubes.
(ACS nano, 2014-08-11)The coexistence of semiconducting and metallic single-walled carbon nanotubes (SWNTs) during synthesis is one of the major bottlenecks that prevent their broad application for the next-generation nanoelectronics. Herein, ... -
Interference of chiral Andreev edge states
(Nature Physics, 2020-08-01)© 2020, The Author(s), under exclusive licence to Springer Nature Limited. The search for topological excitations such as Majorana fermions has spurred interest in the boundaries between distinct quantum states. Here, we ... -
Intracellular Neural Recording with Pure Carbon Nanotube Probes.
(PloS one, 2013-01)The computational complexity of the brain depends in part on a neuron's capacity to integrate electrochemical information from vast numbers of synaptic inputs. The measurements of synaptic activity that are crucial ... -
Inverse AC Josephson Effect in Ballistic Multiterminal Graphene Josephson Junctions
In multi-terminal Josephson junctions, the superconducting coupling is established between each pair of contacts across a common normal channel. The state of such junction is described by N-1 independent phase differences ... -
Multiterminal Inverse AC Josephson Effect.
(Nano letters, 2021-11-15)When a Josephson junction is exposed to microwave radiation, it undergoes the inverse AC Josephson effect─the phase of the junction locks to the drive frequency. As a result, the I-V curves of the junction acquire "Shapiro ... -
Quantum Hall-based superconducting interference device.
(Science Advances, 2019-09-13)We present a study of a graphene-based Josephson junction with dedicated side gates carved from the same sheet of graphene as the junction itself. These side gates are highly efficient and allow us to modulate carrier density ... -
Quantum phase transition in a resonant level coupled to interacting leads.
(Nature, 2012-08)A Luttinger liquid is an interacting one-dimensional electronic system, quite distinct from the 'conventional' Fermi liquids formed by interacting electrons in two and three dimensions. Some of the most striking properties ... -
Rhodium nanoparticles for ultraviolet plasmonics.
(Nano Lett, 2015-02-11)The nonoxidizing catalytic noble metal rhodium is introduced for ultraviolet plasmonics. Planar tripods of 8 nm Rh nanoparticles, synthesized by a modified polyol reduction method, have a calculated local surface plasmon ... -
Self-Assembling DNA templates for programmed artificial biomineralization
(Soft Matter, 2011-05-16)Complex materials with micron-scale dimensions and nanometre-scale feature resolution created via engineered DNA self-assembly represent an important new class of soft matter. These assemblies are increasingly being exploited ... -
Supercurrent Flow in Multiterminal Graphene Josephson Junctions.
(Nano letters, 2019-02)We investigate the electronic properties of ballistic planar Josephson junctions with multiple superconducting terminals. Our devices consist of monolayer graphene encapsulated in boron nitride with molybdenum-rhenium contacts. ... -
Switching currents limited by single phase slips in one-dimensional superconducting Al nanowires.
(Physical review letters, 2011-09-21)An aluminum nanowire switches from superconducting to normal as the current is increased in an upsweep. The switching current (I(s)) averaged over upsweeps approximately follows the depairing critical current (I(c)) but ... -
Zero Crossing Steps and Anomalous Shapiro Maps in Graphene Josephson Junctions.
(Nano letters, 2020-10)The AC Josephson effect manifests itself in the form of "Shapiro steps" of quantized voltage in Josephson junctions subject to radiofrequency (RF) radiation. This effect presents an early example of a driven-dissipative ...
