In-plane gate induced transition asymmetry of spin-resolved Landau levels in InAs-based quantum wells
Olivio Chiatti, Johannes Boy, Christian Heyn +2
The cross-over from quasi-two- to quasi-one-dimensional electron transport subject to transverse electric fields and perpendicular magnetic fields are studied in the diffusive to q…
Three-Terminal Energy Harvester with Coupled Quantum Dots
Holger Thierschmann, Rafael Sánchez, Björn Sothmann +5
Rectification of thermal fluctuations in mesoscopic conductors is the key idea of today's attempts to build nanoscale thermoelectric energy harvesters in order to convert heat into…
Thermal Gating of Charge Currents with Coulomb Coupled Quantum Dots
Holger Thierschmann, Fabian Arnold, Marcel Mittermüller +5
We have observed thermal gating, i.e. electrostatic gating induced by hot electrons. The effect occurs in a device consisting of two capacitively coupled quantum dots. The double d…
Electrical and terahertz magnetospectroscopy studies of laser-patterned micro- and nanostructures on InAs-based heterostructures
Olivio Chiatti, Sven S. Buchholz, Christian Heyn +4
Nanostructures fabricated from narrow-gap semiconductors with strong spin-orbit interaction (SOI), such as InAs, can be used to filter momentum modes of electrons and offer the pos…
Anomalous magnetotransport and cyclotron resonance of high mobility magnetic 2DHGs in the quantum Hall regime
U. Wurstbauer, S. Knott, C. G. v. Westarp +5
Low temperature magnetotransport measurements and far infrared transmission spectroscopy are reported in molecular beam epitaxial grown two-dimensional hole systems confined in str…
Spin-wave interference in three-dimensional rolled-up ferromagnetic microtubes
Felix Balhorn, Sebastian Mansfeld, Andreas Krohn +4
We have investigated spin-wave excitations in rolled-up Permalloy microtubes using microwave absorption spectroscopy. We find a series of quantized azimuthal modes which arise from…
