Development of a Mechanical Single Electron Shuttle — •Darren Southworth and Eva Weig — Ludwig-Maximilians-Universität, Fakultät für Physik, München

We present progress in the development of a mechanical single electron shuttle. The shuttle is composed of a gold island on a silicon nitride beam situated in a gap between source and drain electrodes. Oscillation of the beam brings the island into contact with the electrodes, and in the presence of a DC bias, charging of the island results in electron transport. The island is equipped with a gate electrode and the motion of the beam can be driven dielectrically. The current design has potential to function as a mechanical single electron transistor at 4K.
