Abstract
A sensor for electromagnetic quantities includes a bistable device whose residence times in the stable states depend on the electromagnetic quantity. The bistable device further includes a switching zone, whose dimension in the direction of a current of charge carriers is smaller than the ballistic mean free path of the charge carriers within the switching zone. An analyzer circuit may be used for generating a sensor output signal depending on the residence times of the bistable device for measuring the electromagnetic quantity. The switching device may be a resonant tunneling diode or a Y-branch nanojunction.
