Magnetic Field Induced Instabilities in Localised Two-Dimensional Electron Systems
M. Baenninger, A. Ghosh, M. Pepper +3
We report density dependent instabilities in the localised regime of mesoscopic two-dimensional electron systems (2DES) with intermediate strength of background disorder. They are…
Field-tunable magnetic phases in a semiconductor-based two-dimensional Kondo lattice
C. Siegert, A. Ghosh, M. Pepper +4
We show the existence of intrinsic localized spins in mesoscopic high-mobility GaAs/AlGaAs heterostructures. Non-equilibrium transport spectroscopy reveals a quasi-regular distribu…
Sensitivity of the magnetic state of a spin lattice on itinerant electron orbital phase
C. Siegert, A. Ghosh, M. Pepper +4
Spatially extended localized spins can interact via indirect exchange interaction through Friedel oscillations in the Fermi sea. In arrays of localized spins such interaction can l…
Local transport in a disorder-stabilized correlated insulating phase
M. Baenninger, A. Ghosh, M. Pepper +4
We report the experimental realization of a correlated insulating phase in 2D GaAs/AlGaAs heterostructures at low electron densities in a limited window of background disorder. Thi…
Zero-bias anomaly and Kondo-assisted quasi-ballistic 2D transport
Arindam Ghosh, Matthew Wright, Christophe Siegert +4
Nonequilibrium transport measurements in mesoscopic quasi-ballistic 2D electron systems show an enhancement in the differential conductance around the Fermi energy. At very low tem…
A dynamic localization of 2D electrons at mesoscopic length scales
A. Ghosh, M. Pepper, H. E. Beere +1
We have investigated the local magneto-transport in high-quality 2D electron systems at low carrier densities. The positive magneto-resistance in perpendicular magnetic field in th…
