Charge Pumping in Carbon Nanotubes [PDF]
Physical Review Letters, 2005 We demonstrate charge pumping in semiconducting carbon nanotubes by a traveling potential wave. From the observation of pumping in the nanotube insulating state we deduce that transport occurs by packets of charge being carried along by the wave. By tuning the potential of a side gate, transport of either electron or hole packets can be realized ...

Streamlined Fibonacci Charge Pump [PDF]
2020 International Conference on Applied Electronics (AE), 2020 This paper is devoted to questions of the efficiency increase of the Fibonacci charge pump (FCP). The main attention is dedicated to discovering the mechanism of the power losses in the given FCP structure. The FCP after reduction of the power losses has a flatter efficiency characteristic than the original FCP structure.

Parallel quantized charge pumping [PDF]
Physical Review B, 2009 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 frequency. With the application of a perpendicular magnetic field the accuracy of quantization is shown to be $< $20 ppm for a current of $108.9 $pA.
