Single electron pumping in InAs nanowire double quantum dots
(2007) In Applied Physics Letters 91(5). p.1-052109- Abstract
- Closely spaced local gate electrodes are used to electrically define a double quantum dot along an InAs nanowire crystal. By applying a periodic pulse sequence to two plunger gate electrodes controlling the double quantum dot charge configuration, the device is operated as a single electron pump. The authors find that within measurement accuracy, the pumping current equals one electron per cycle for frequencies up to 2 MHz, demonstrating the suitability of nanowire based quantum dots for pumping applications.
