Controlled generation and detection of a thermal bias in Corbino devices under the quantum Hall regime
Mariano A. Real, Alejandra Tonina, Liliana Arrachea +4
We present an experimental technique to generate and measure a temperature bias in the quantum Hall effect of GaAs/AlGaAs Corbino samples. The bias is generated by injecting an ele…
Thermoelectricity in Quantum-Hall Corbino Structures
Mariano Real, Daniel Gresta, Christian Reichl +6
We measure the thermoelectric response of Corbino structures in the quantum Hall effect regime and compare it with a theoretical analysis. The measured thermoelectric voltages are…
Ballistic transport in graphene antidot lattices
Andreas Sandner, Tobias Preis, Christian Schell +5
Graphene samples can have a very high carrier mobility if influences from the substrate and the environment are minimized. Embedding a graphene sheet into a heterostructure with he…
Evidence of spontaneous spin polarization in the two-dimensional electron gas
A. R. Goñi, P. Giudici, F. A. Reboredo +4
Density-functional calculations using an exact exchange potential for a two-dimensional electron gas (2DEG) formed in a GaAs single quantum well predict the existence of a spin-pol…
