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…
Thermoelectric cooling properties of a quantum Hall Corbino device
Juan Herrera Mateos, Mariano A. Real, Christian Reichl +4
We analyze the thermoelectric cooling properties of a Corbino device in the quantum Hall regime on the basis of experimental data of electrical conductance. We focus on the cooling…
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…
Optimal thermoelectricity with quantum spin-Hall edge states
Daniel Gresta, Mariano Real, Liliana Arrachea
We study the thermoelectric properties of a Kramers pair of helical edge states of the quantum spin Hall effect coupled to a nanomagnet with a component of the magnetization perpen…
Low Carrier Density Epitaxial Graphene Devices On SiC
Yanfei Yang, Lung-I Huang, Yasuhiro Fukuyama +6
Monolayer epitaxial graphene (EG) grown on hexagonal Si-terminated SiC substrates is intrinsically electron-doped (carrier density is about 10^13 cm^(-2)). We demonstrate a clean d…
