Low-temperature magnetoresistance hysteresis in Vanadium-doped BiTeSe bulk topological insulators
Birkan Düzel, Christian Riha, Karl Graser +2
BiTeSe single crystals show gapless topological surface states and doping () with Vanadium allows to shift the chemical potential in the bulk band gap. Acc…
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…
Excess noise in AlGaAs/GaAs based quantum rings
Christian Riha, Sven S. Buchholz, Olivio Chiatti +3
Cross-correlated noise measurements are performed in etched AlGaAs/GaAs based quantum rings in equilibrium at bath temperature of $T_\text{bath}=4.2\tex…
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…
Mode-selected heat flow through a one-dimensional waveguide network
Christian Riha, Philipp Miechowski, Sven S. Buchholz +4
Cross-correlated measurements of thermal noise are performed to determine the electron temperature in nanopatterned channels of a GaAs/AlGaAs heterostructure at 4.2 K. Two-dimensio…
Noise thermometry in narrow 2D electron gas heat baths connected to a quasi-1D interferometer
Sven S. Buchholz, Elmar Sternemann, Olivio Chiatti +3
Thermal voltage noise measurements are performed in order to determine the electron temperature in nanopatterned channels of a GaAs/AlGaAs heterostructure at bath temperatures of 4…
