Spin blockade in ground state resonance of a quantum dot
A. K. Huettel, H. Qin, A. W. Holleitner +5
We present measurements on spin blockade in a laterally integrated quantum dot. The dot is tuned into the regime of strong Coulomb blockade, confining ~ 50 electrons. At certain el…
Hopping conductivity in heavily doped n-type GaAs layers in the quantum Hall effect regime
S. S. Murzin, M. Weiss, A. G. M. Jansen +1
We investigate the magnetoresistance of epitaxially grown, heavily doped n-type GaAs layers with thickness (40-50 nm) larger than the electronic mean free path (23 nm). The tempera…
Frictional Drag Between Coupled 2D Hole Gases in GaAs/AlGaAs Heterostructures
C. Joerger, S. J. Cheng, H. Rubel +5
We report on the first measurements of the drag effect between coupled 2D-hole gases. We investigate the coupling by changing the carrier densities in the quantum wells, the widths…
Magneto-optical evidence of the percolation nature of the metal-insulator transition in the 2D electron system
I. V. Kukushkin, Vladimir I. Fal'ko, R. J. Haug +2
We compare the results of the transport and time-resolved magneto-luminescence measurements in disordered 2D electron systems in GaAs-AlGaAs heterostructures in the extreme quantum…
