Abstract :
We report on a nanomechanical bi-polar current switch realized by vertical silicon nanopillars. A gold layer deposited on top of the nanopillars provides with the conduction path for electrons. For achieving maximal charging energy of the system, the electron islands are placed in series. Device operation is demonstrated under vacuum at room temperature. Adjusting the oscillation frequency of the coupled nanopillars allows for the application of the system to a bi-polar current switch.
