- Abstract
- A novel single electron pump based on individual molecules (a single wall carbon nanotube) is discussed in terms of the hybrid superconducting normal conducting pumping principle A concept demonstration device has been built based on a carbon nanotube contacted by Nb-Ti leads Charge current quantization is achieved through rf modulation of the back gate voltage The device is able to transfer a given number of electrons per pumping cycle Single electron pumping is achieved for pumping frequencies up to 80 MHz
