Patent ID: 8134220

Claim:
A two-terminal switching device, comprising: a first conductive terminal extending up from a substrate; a second conductive terminal extending up from the substrate, the second conductive terminal in spaced relation to the first terminal, wherein the spaced relation defines a void in the substrate; a nanotube article having at least one nanotube, said article being arranged to permanently contact at least a portion of the first and second terminals and partially suspended over the void; and a stimulus circuit in electrical communication with at least one of the first and second terminals, said stimulus circuit generating and applying selected waveforms to at least one of the first and second terminals to induce a change in the resistance of the device between the first and second terminals between a relatively low resistance and a relatively high resistance, wherein the relatively high resistance between the first and second terminals corresponds to a first state of the device, and wherein the relatively low resistance between the first and second terminals corresponds to a second state of the device.
