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…
