Ultrasensitive Photoresponse of Graphene Quantum Dot in the Coulomb Blockade Regime to THz Radiation
E. Riccardi, S. Massabeau, F. Valmorra +11
Graphene quantum dots (GQDs) have recently attracted considerable attention, with appealing properties for terahertz (THz) technology. This includes the demonstration of large ther…
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…
Low frequency elastic measurements on solid He in Vycor using a torsional oscillator
A. D. Fefferman, J. R. Beamish, A. Haziot +1
Torsional oscillator experiments involving solid He confined in the nanoscale pores of Vycor glass showed anomalous frequency changes at temperatures below 200 mK. These were…
Dislocation networks in helium-4 crystals
A. D. Fefferman, F. Souris, A. Haziot +2
The mechanical behavior of crystals is dominated by dislocation networks, their structure and their interactions with impurities or thermal phonons. However, in classical crystals,…
Critical dislocation speed in helium-4 crystals
Ariel Haziot, Andrew Fefferman, Fabien Souris +3
Our experiments show that in He crystals, the binding of He impurities to dislocations does not necessarily imply their pinning. Indeed, in these crystals, there are two di…
The giant plasticity of a quantum crystal
Ariel Haziot, Xavier Rojas, Andrew D. Fefferman +2
When submitted to large stresses at high temperature, usual crystals may irreversibly deform. This phenomenon is known as plasticity and it is due to the motion of crystal defects…
