Donor implanted Back-gates in GaAs for MBE-grown highest mobility two-dimensional electron systems
Jan Scharnetzky, Philipp Baumann, Christian Reichl +3
Three different elements, Silicon, Selenium, and Tellurium, are ion-implanted in Gallium arsenide to form a conducting layer that serves as a back-gate to a molecular beam epitaxy…
The improved inverted AlGaAs/GaAs interface: its relevance for high-mobility quantum wells and hybrid systems
Elcin Külah, Christian Reichl, Jan Scharnetzky +3
Two dimensional electron gases (2DEGs) realized at GaAs/AlGaAs single interfaces by molecular-beam epitaxy (MBE) reach mobilities of about 15 million cm^2/Vs if the AlGaAs alloy is…
Local signatures of electron-electron scattering in an electronic cavity
Carolin Gold, Beat A. Bräm, Richard Steinacher +7
We image equilibrium and non-equilibrium transport through a two-dimensional electronic cavity using scanning gate microscopy (SGM). Injecting electrons into the cavity through a q…
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…
