Large magnetoresistance by Pauli blockade in hydrogenated graphene
J. Guillemette, N. Hemsworth, A. Vlasov +9
We report the observation of a giant positive magnetoresistance in millimetre scale hydrogenated graphene with magnetic field oriented in the plane of the graphene sheet. A positiv…
Magnetic refrigeration with paramagnetic semiconductors at cryogenic temperatures
A. Vlasov, J. Guillemette, G. Gervais +1
We propose paramagnetic semiconductors as active media for refrigeration at cryogenic temperatures by adiabatic demagnetization. The paramagnetism of impurity dopants or structural…
Dephasing in strongly anisotropic black phosphorus
N. Hemsworth, V. Tayari, F. Telesio +9
Weak localization was observed and determined in a black phosphorus (bP) field-effect transistor 65 nm thick. The weak localization behaviour was found to be in excellent agreement…
Second Landau Level Fractional Quantum Hall Effects in the Corbino Geometry
B. A. Schmidt, K. Bennaceur, S. Bilodeau +3
For certain measurements, the Corbino geometry has a distinct advantage over the Hall and van der Pauw geometries, in that it provides a direct probe of the bulk 2DEG without compl…
Hydrodynamics of Superfluid Helium in a Single Nanohole
M. Savard, G. Dauphinais, G. Gervais
The flow of liquid helium through a single nanohole with radius smaller than 25 nm was studied for the first time. Mass flow was induced by applying a pressure difference of up to…
Quantum-Classical Crossover and Apparent Metal-Insulator Transition in a Weakly Interacting 2D Fermi Liquid
Xiaoqing Zhou, B. Schmidt, C. Proust +4
We report the observation of a parallel magnetic field induced metal-insulator transition (MIT) in a high-mobility two-dimensional electron gas (2DEG) for which spin and localizati…
