Nanotube transfer devices controllably form a nanotube-based electrically conductive channel between a first node and a second node under the control of a control structure. A control structure induces a nanotube channel element to deflect so as to form and unform the conductive channel between the nodes. The nanotube channel element is not in permanent electrical contact with either the first node or the second node. The nanotube channel element may have a floating potential in certain states of the device. Each output node may be connected to an arbitrary network of electrical components. The nanotube transfer device may be volatile or non-volatile. In preferred embodiments, the nanotube transfer device is a three-terminal device or a four-terminal device. Electrical circuits are provided that ensure proper switching of nanotube transfer devices interconnected with arbitrary circuits. The circuits may overdrive the control structure to induce the desired state of channel information.

Dispositifs de transferts utilisant des nanotubes formant un canal électriquement conducteur utilisant des nanotubes entre un premier noeud et un second noeud sous le contrôle d'une structure de commande. Celle-ci induit la déviation d'un élément de canal de nanotube de sorte à former et déformer le canal conducteur entre les noeuds. Cet élément n'est pas en contact électrique permanent avec le premier ou le second noeud. Il peut comporter un potentiel de flottaison dans certains états du dispositif. Chaque noeud de sortie peut être connecté à un réseau arbitraire de composants électriques. Le dispositif de transfert peut être volatil ou non. Dans des modes de réalisation préférés, le dispositif de transfert utilisant des nanotubes est un dispositif à trois terminaux ou un dispositif à quatre terminaux. Des circuits électriques garantissent la commutation correcte des dispositifs de transfert utilisant des nanotubes connectés à des circuits arbitraires. Les circuits peuvent surexciter la structure de commande afin d'induire l'état souhaité de formation de canal.
