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…
Superballistic electron flow through a point contact in a Ga[Al]As heterostructure
Lev V. Ginzburg, Carolin Gold, Marc P. Röösli +5
We measure electronic transport through point contacts in the high-mobility electron gas in a Ga[Al]As heterostructure at different temperatures and bulk electron densities. The co…
Imaging signatures of the local density of states in an electronic cavity
Carolin Gold, Beat A. Bräm, Michael S. Ferguson +9
We use Scanning Gate Microscopy to study electron transport through an open, gate-defined resonator in a Ga(Al)As heterostructure. Raster-scanning the voltage-biased metallic tip a…
Realization of a Qubit: energy spectroscopy and coherence
Benedikt Kratochwil, Jonne V. Koski, Andreas J. Landig +9
The energy landscape of a single electron in a triple quantum dot can be tuned such that the energy separation between ground and excited states becomes a flat function of the rele…
Fractional Coulomb blockade for quasiparticle tunneling between edge channels
Marc P. Röösli, Michael Hug, Giorgio Nicolí +6
We study the magneto-conductance of a -wide quantum dot in the fractional quantum Hall regime. For a filling factor and in the quantum…
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…
