Non-invasive probing of random local potential fluctuations in ZnCdSe/ZnSe quantum wells
D. A. Fuhrmann, H. J. Krenner, A. Wixforth +4
Temperature dependence and recombination behavior of trapped charge carriers in ZnCdSe/ZnSe multiple quantum wells are investigated employing surface acoustic waves. These weakly p…
Theoretical and experimental investigations of Coulomb blockade in coupled quantum dot systems
F. J. Kaiser, S. Kohler, P. Hänggi +7
Two strongly coupled quantum dots are theoretically and experimentally investigated. In the conductance measurements of a GaAs based low-dimensional system additional features to t…
Acoustoelectric current transport through single-walled carbon nanotubes
J. Ebbecke, C. J. Strobl, A. Wixforth
We have contacted single-walled carbon nanotubes after aligning the tubes by the use of surface acoustic waves. The acoustoelectric current has been measured at 4.2 K and a probing…
Quantized charge pumping through a quantum dot by surface acoustic waves
J. Ebbecke, N. E. Fletcher, T. J. B. M. Janssen +4
We present a realization of quantized charge pumping. A lateral quantum dot is defined by metallic split gates in a GaAs/AlGaAs heterostructure. A surface acoustic wave whose wavel…
Quantized charge transport through a static quantum dot using a surface acoustic wave
N. E. Fletcher, J. Ebbecke, T. J. B. M. Janssen +4
We present a detailed study of the surface acoustic wave mediated quantized transport of electrons through a split gate device containing an impurity potential defined quantum dot…
Enhanced quantized current driven by surface acoustic waves
J. Ebbecke, G. Bastian, M. Blöcker +2
We present the experimental realization of different approaches to increase the amount of quantized current which is driven by surface acoustic waves through split gate structures…
