Robust single-parameter quantized charge pumping
B. Kaestner, V. Kashcheyevs, G. Hein +3
This paper investigates a scheme for quantized charge pumping based on single-parameter modulation. The device was realized in an AlGaAs-GaAs gated nanowire. We find a remarkable r…
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…
Single-parameter non-adiabatic quantized charge pumping
B. Kaestner, V. Kashcheyevs, S. Amakawa +8
Controlled charge pumping in an AlGaAs/GaAs gated nanowire by single-parameter modulation is studied experimentally and theoretically. Transfer of integral multiples of the element…
Shot noise in tunneling through a single quantum dot
A. Nauen, F. Hohls, N. Maire +2
We investigate the noise properties of a zero-dimensional InAs quantum dot (QD) embedded in a GaAs-AlAs-GaAs tunneling structure. We observe an approximately linear dependence of t…
