Single- and few-electron dynamic quantum dots in a perpendicular magnetic field
S. J. Wright, A. L. Thorn, M. D. Blumenthal +9
We present experimental studies of the current pumped through a dynamic quantum dot over a wide range of magnetic fields. At low fields we observe repeatable structure indicating i…
Accurate high speed single-electron quantum dot preparation
S. P. Giblin, S. J. Wright, J. Fletcher +7
Using standard microfabrication techniques it is now possible to construct devices, which appear to reliably manipulate electrons one at a time. These devices have potential use as…
Parallel quantized charge pumping
S. J. Wright, M. D. Blumenthal, M. Pepper +4
Two quantized charge pumps are operated in parallel. The total current generated is shown to be far more accurate than the current produced with just one pump operating at a higher…
Enhanced current quantization in high frequency electron pumps in a perpendicular magnetic field
S. J. Wright, M. D. Blumenthal, Godfrey Gumbs +8
We present experimental results of high frequency quantized charge pumping through a quantum dot formed by the electric field arising from applied voltages in a GaAs/AlGaAs system…
