Anisotropic and strong negative magneto-resistance in the three-dimensional topological insulator Bi2Se3
S. Wiedmann, A. Jost, B. Fauque +10
We report on high-field angle-dependent magneto-transport measurements on epitaxial thin films of Bi2Se3, a three-dimensional topological insulator. At low temperature, we observe…
Temperature-driven transition from a semiconductor to a topological insulator
Steffen Wiedmann, Andreas Jost, Cornelius Thienel +6
We report on a temperature-induced transition from a conventional semiconductor to a two-dimensional topological insulator investigated by means of magnetotransport experiments on…
Magneto Seebeck effect in REFeAsO (RE=rare earth) compounds: probing the magnon drag scenario
F. Caglieris, A. Braggio, I. Pallecchi +8
We investigate Seebeck effect in REFeAsO (RE=rare earth)compounds as a function of temperature and magnetic field up to 30T. The Seebeck curves are characterized by a broad negativ…
Transport and thermoelectric properties of the LaAlO/SrTiO interface
A. Jost, V. K. Guduru, S. Wiedmann +5
The transport and thermoelectric properties of the interface between SrTiO and a 26-monolayer thick LaAlO-layer grown at high oxygen-pressure have been investigated at temp…
Thermally excited multi-band conduction in LaAlO3/SrTiO3 heterostructures exhibiting magnetic scattering
V. K. Guduru, A. McCollam, A. Jost +5
Magnetotransport measurements of charge carriers at the interface of a LaAlO3/SrTiO3 heterostructure with 26 unit cells of LaAlO3 show Hall resistance and magnetoresistance which a…
