Thermoelectricity in Quantum Hall Corbino Structures

We measure the thermoelectric response of Corbino structures in the quantum Hall effect regime and compare it with a theoretical analysis.

Optimal Thermoelectricity with Quantum Spin Hall Edge States

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 perpendicular to the direction of the spin-orbit interaction of the host.

Determination of Voltage Dependence in High-Voltage Standard Capacitors

The voltage coefficient of compressed gas capacitors is a relevant parameter in high-voltage calibrations. These capacitors, used as standards, are calibrated at low voltages so it is necessary to know their variation when they are used at high voltages.

Low Carrier Density Epitaxial Graphene Devices On SiC

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 device fabrication process using a precious-metal protective layer.
