Bulk Thermal Conductance of the 5/2 and 7/3 Fractional Quantum Hall States in the Corbino Geometry
F. Boivin, M. Petrescu, Z. Berkson-Korenberg +2
In this work, making use of time-resolved in situ Joule heating of a two-dimensional electron gas (2DEG) in the Corbino geometry, we report bulk thermal conductance measurements fo…
Total Faraday rotation by the Hall effect in a 2D electron gas
Vishnunarayanan Suresh, Talia J. Martz-Oberlander, Sujatha Vijayakrishnan +5
We report the realization of near total Faraday rotation of =1.43 rad (82 degrees) on a single pass through a 2D electron gas (2DEG), approaching the ideal limit of rad…
Observation of Temperature Independent Anomalous Hall Effect in Thin Bismuth from Near Absolute Zero to 300 K Temperature
Oulin Yu, F. Boivin, A. Silberztein +1
We report our discovery of a temperature independent anomalous Hall effect (AHE) from 15 mK to 300 K temperature occurring in a 68 nm thick transport device made out of pure bismut…
Two-dimensional hydrodynamic viscous electron flow in annular Corbino rings
Sujatha Vijayakrishnan, Z. Berkson-Korenberg, J. Mainville +5
The concept of fluidic viscosity is ubiquitous in our everyday life and for it to arise the fluidic medium must necessarily form a continuum where macroscopic properties can emerge…
Anomalous Hall Effect in Thin Bismuth
Oulin Yu, Sujatha Vijayakrishnan, R. Allgayer +2
Bismuth, the heaviest of all group V elements with strong spin-orbit coupling, is famously known to exhibit many interesting transport properties, and effects such as Shubnikov-de…
Large composite fermion effective mass at filling factor 5/2
M. Petrescu, Z. Berkson-Korenberg, Sujatha Vijayakrishnan +3
The 5/2 fractional quantum Hall effect in the second Landau level of extremely clean two-dimensional electron gases has attracted much attention due to its topological order predic…
Method of Mechanical Exfoliation of Bismuth with Micro-Trench Structures
Oulin Yu, Raphaela Allgayer, Simon Godin +5
The discovery of graphene led to a burst in search for 2D materials originating from layered atomic crystals coupled by van der Waals force. While bulk bismuth crystals share this…
Competing charge density waves probed by non-linear transport and noise in the second and third Landau levels
K. Bennaceur, C. Lupien, B. Reulet +3
Charge density waves (CDW) in the second and third Landau levels (LL) are investigated by both non-linear electronic transport and noise. The use of a Corbino geometry ensures that…
