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…
