Disclosed is a triple-gate or multi-gate component based on the quantum mechanical tunnel effect. The component comprises at least two tunneling electrodes on a substrate that are separated by a gap through which electrons can tunnel. The component comprises an arrangement for applying an electric field to the gap, which is such that the path of an electron tunneling between the tunneling electrodes is elongated as a result of the deflection caused by this field. In general, an arrangement can also be provided for applying an electric field to the gap, this electric field having a field component that is perpendicular to the direction of the tunnel current between the tunneling electrodes and is parallel to the substrate. Since the tunnel current between the tunneling electrodes exponentially depends on the distance traveled by the electrons in the gap, such an electric field has a penetration effect on the tunneling probability and thus on the tunnel current to be controlled. Such a component can act as a very fast switching transistor having high amplification and does not have to be semiconducting.
