Patent ID: 8253171

Claim:
A two terminal switching device, comprising: a first conductive terminal; a second conductive terminal in spaced relation to the first terminal; the first terminal encompassed by the second terminal; an electrically insulating spacer, the spacer encompassing the first terminal and providing the spaced relation between the second terminal and the first terminal; a nanotube article comprising at least one carbon nanotube, the nanotube article being arranged to overlap at least a portion of each of the first and second terminals; and a stimulus circuit in electrical communication with at least one of the first and second terminals, the stimulus circuit capable of applying a first electrical stimulus to at least one of the first and second terminals to change the resistance of the device as formed between the first and second terminals from a relatively lower first resistance to a relatively higher second resistance, the stimulus circuit capable of applying a second electrical stimulus to at least one of the first and second terminals to change the resistance of the device as formed between the first and second terminals from the relatively higher second resistance to the relatively lower first resistance, wherein the relatively higher second resistance between the first and second terminals corresponds to an “OFF” state of the device, and wherein the relatively lower first resistance between the first and second terminals corresponds to an “ON” state of the device, and wherein the plurality of devices as formed have an initial “ON” state yield and an initial “OFF” state yield.
