A nanoelectromechanical switch consists of two landing electrodes on either side of a movable silicon nanowire, separated by a nanoscale air gap. The bistable mechanical state of the nanowire determines an on/off state, which is sensed by measuring the contact resistance. The n‐type semiconductor electrodes and p‐type nanowire form a p–n junction diode at the cross‐point.
