Patent

CA 2667653

The invention relates to a field emission device comprising a cathode having an emission region (1) for electrons (2). The field emission device is embodied for generating technically useful electron currents at a voltage which is as low as possible, in such a way that the emission region (1) has an arrangement of a plurality of individually positioned or positionable atoms (4) or molecules.

La présente invention concerne un dispositif d'émission de champ comprenant une cathode (3) présentant une zone d'émission (1) pour des électrons (2), le dispositif d'émission de champ étant conçu pour produire des courants d'électrons pouvant faire l'objet d'une utilisation technique pour une tension minimale, de sorte que la zone d'émission (1) présente un agencement de plusieurs atomes (4) ou molécules positionné(e)s ou pouvant être positionné(e)s de façon individuelle.
