The optical absorption in indirect semiconductor to semimetal PtSe2 arises from direct transitions
Marin Tharrault, Sabrine Ayari, Mehdi Arfaoui +12
is a van der Waals material transitioning from an indirect bandgap semiconductor to a semimetal with increasing thickness. Its absorption threshold has been conjectur…
Electroluminescence of the graphene 2D semi-metal
A. Schmitt, L. Abou-Hamdan, M. Tharrault +18
Electroluminescence, a non-thermal radiative process, is ubiquitous in semi-conductors and insulators but fundamentally precluded in metals. We show here that this restriction can…
Velocity and confinement of edge plasmons in HgTe-based 2D topological insulators
Alexandre Gourmelon, Elric Frigerio, Hiroshi Kamata +10
High-frequency transport in the edge states of the quantum spin Hall (QSH) effect has to date rarely been explored, though it could cast light on the scattering mechanisms taking p…
One hundred second bit-flip time in a two-photon dissipative oscillator
C. Berdou, A. Murani, U. Reglade +19
Current implementations of quantum bits (qubits) continue to undergo too many errors to be scaled into useful quantum machines. An emerging strategy is to encode quantum informatio…
Layering transitions in superfluid helium adsorbed on a carbon nanotube mechanical resonator
Adrien Noury, Jorge Vergara-Cruz, Pascal Morfin +5
Helium is recognized as a model system for the study of phase transitions. Of particular interest is the superfluid phase in two dimensions. We report measurements on superfluid he…
Onset of optical-phonon cooling in multilayer graphene revealed by RF noise and black-body radiation thermometries
D. Brunel, S. Berthou, R. Parret +8
We report on electron cooling power measurements in few-layer graphene excited by Joule heating by means of a new setup combining electrical and optical probes of the electron and…
Contact gating at GHz frequency in graphene
Q. Wilmart, A. Inhofer, M. Boukhicha +7
The paradigm of graphene transistors is based on the gate modulation of the channel carrier density by means of a local channel gate. This standard architecture is subject to the s…
Persistent control of a superconducting qubit by stroboscopic measurement feedback
Philippe Campagne-Ibarcq, Emmanuel Flurin, Nicolas Roch +6
Making a system state follow a prescribed trajectory despite fluctuations and errors commonly consists in monitoring an observable (temperature, blood-glucose level...) and reactin…
Widely tunable, non-degenerate three-wave mixing microwave device operating near the quantum limit
Nicolas Roch, Emmanuel Flurin, François Nguyen +4
We present the first experimental realization of a widely frequency tunable, non-degenerate three-wave mixing device for quantum signals at GHz frequency. It is based on a new supe…
Revealing the electronic structure of a carbon nanotube carrying a supercurrent
Jean-Damien Pillet, Charis Quay, Pascal Morfin +3
Carbon nanotubes (CNTs) are not intrinsically superconducting but they can carry a supercurrent when connected to superconducting electrodes. This supercurrent is mainly transmitte…
Conserved spin and orbital phase along carbon nanotubes connected with multiple ferromagnetic contacts
C. Feuillet-Palma, T. Delattre, P. Morfin +6
We report on spin dependent transport measurements in carbon nanotubes based multi-terminal circuits. We observe a gate-controlled spin signal in non-local voltages and an anomalou…
Single Carbon Nanotube Transistor at GHz Frequency
Julien Chaste, Lorenz Lechner, Pascal Morfin +7
We report on microwave operation of top-gated single carbon nanotube transistors. From transmission measurements in the 0.1-1.6 GHz range, we deduce device transconductance gm and…
Shot noise in carbon nanotube based Fabry-Perot interferometers
L. G. Herrmann, T. Delattre, P. Morfin +4
We report on shot noise measurements in carbon nanotube based Fabry-Perot electronic interferometers. As a consequence of quantum interferences, the noise power spectral density os…
