Edge currents shunt the insulating bulk in gapped graphene
M. J. Zhu, A. V. Kretinin, M. D. Thompson +13
An energy gap can be opened in the electronic spectrum of graphene by lifting its sublattice symmetry. In bilayers, it is possible to open gaps as large as 0.2 eV. However, these g…
Interplay of the inverse proximity effect and magnetic field in out-of-equilibrium single-electron devices
Shuji Nakamura, Yuri A. Pashkin, Mathieu Taupin +11
The magnetic field is shown to affect significantly non-equilibrium quasiparticle (QP) distributions under conditions of inverse proximity effect on the remarkable example of a sin…
Polariton pattern formation and photon statistics of the associated emission
C. E. Whittaker, B. Dzurnak, O. A. Egorov +8
We report on the formation of a diverse family of transverse spatial polygon patterns in a microcavity polariton fluid under coherent driving by a blue-detuned pump. Patterns emerg…
Cross-plane enhanced thermoelectricity and phonon suppression in graphene/MoS2 van der Waals heterostructures
Hatef Sadeghi, Sara Sangtarash, Colin J. Lambert
The thermoelectric figures of merit of pristine two-dimensional materials are predicted to be significantly less than unity, making them uncompetitive as thermoelectric materials.…
On-chip magnetic cooling of a nanoelectronic device
D. I. Bradley, A. M. Guénault, D. Gunnarsson +8
We demonstrate significant cooling of electrons in a nanostructure below 10 mK by demagnetisation of thin-film copper on a silicon chip. Our approach overcomes the typical bottlene…
Sonic Landau-level lasing and synthetic gauge fields in mechanical metamaterials
Hamed Abbaszadeh, Anton Souslov, Jayson Paulose +2
Mechanical strain can lead to a synthetic gauge field that controls the dynamics of electrons in graphene sheets as well as light in photonic crystals. Here, we show how to enginee…
Quantum Interference in Graphene Nanoconstrictions
Pascal Gehring, Hatef Sadeghi, Sara Sangtarash +7
We report quantum interference effects in the electrical conductance of chemical vapor deposited graphene nanoconstrictions fabricated using feedback controlled electroburning. The…
Effect of interactions on quantum-limited detectors
Gleb Skorobagatko, Anton Bruch, Silvia Viola Kusminskiy +1
We consider the effect of electron-electron interactions on a voltage biased quantum point contact in the tunneling regime used as a detector of a nearby qubit. We model the leads…
Magnetic ratchet effect in bilayer graphene
Narjes Kheirabadi, Edward McCann, Vladimir I. Fal'ko
We consider the orbital effect of an in-plane magnetic field on electrons in bilayer graphene, deriving linear-in-field contributions to the low-energy Hamiltonian arising from the…
Scaling approach to tight-binding transport in realistic graphene devices: the case of transverse magnetic focusing
M. Beconcini, S. Valentini, R. Krishna Kumar +5
Ultra-clean graphene sheets encapsulated between hexagonal boron nitride crystals host two-dimensional electron systems in which low-temperature transport is solely limited by the…
Asymmetry-induced resistive switching in Ag-AgS-Ag memristors enabling a simplified atomic-scale memory design
A. Gubicza, D. Zs. Manrique, L. Pósa +4
Prevailing models of resistive switching arising from electrochemical formation of conducting filaments across solid state ionic conductors commonly attribute the observed polarity…
Zero-energy modes and valley asymmetry in the Hofstadter spectrum of bilayer graphene van der Waals heterostructures with hBN
Xi Chen, J. R. Wallbank, M. Mucha-Kruczynski +2
We investigate the magnetic minibands of a heterostructure consisting of bilayer graphene (BLG) and hexagonal boron nitride (hBN) by numerically diagonalizing a two-band Hamiltonia…
Exploring quantum interference in heteroatom-substituted graphene-like molecules
Sara Sangtarash, Hatef Sadeghi, Colin J. Lambert
If design principles for controlling quantum interference in single molecules could be elucidated and verified, then this will lay the foundations for exploiting such effects in na…
Precursor configurations and post-rupture evolution of Ag-CO-Ag single-molecule junctions
Zoltán Balogh, Dávid Visontai, Péter Makk +5
Experimental correlation analysis and first-principles theory are used to probe the structure and evolution of Ag-CO-Ag single-molecule junctions, both before the formation, and af…
Gating of single molecule junction conductance by charge transfer complex formation
Andrea Vezzoli, Iain Grace, Carly Brooke +5
The solid-state structures of organic charge transfer (CT) salts are critical in determining their mode of charge transport, and hence their unusual electrical properties, which ra…
