Abstract
Nanotube-based switching elements and logic circuits. Under one embodiment of the invention, a switching element includes an input node, an output node, a nanotube channel element having at least one electrically conductive nanotube, and a control electrode. The control electrode is disposed in relation to the nanotube channel element to controllably form an electrically conductive channel between the input node and the output node. The channel at least includes said nanotube channel element. The output node is constructed and arranged so that channel formation is substantially unaffected by the electrical state of the output node. Under another embodiment of the invention, the control electrode is arranged in relation to the nanotube channel element to form said conductive channel by causing electromechanical deflection of said nanotube channel element. Under another embodiment of the invention, the output node includes an isolation structure disposed in relation to the nanotube channel element so that channel formation is substantially invariant from the state of the output node. Under another embodiment of the invention, the isolation structure includes electrodes disposed on op…
