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…
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…
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…
