    摘要： New devices having horizontally-disposed nanofabric articles and methods of making same are described. A discrete electro-mechanical device includes a structure having an electrically-conductive trace. A defined patch of nanotube fabric is disposed in spaced relation to the trace; and the defined patch of nanotube fabric is electromechanically deflectable between a first and second state. In the first state, the nanotube article is in spaced relation relative to the trace, and in the second state the nanotube article is in contact with the trace. A low resistance signal path is in electrical communication with the defined patch of nanofabric. Under certain embodiments, the structure includes a defined gap into which the electrically conductive trace is disposed. The defined gap has a defined width, and the defined patch of nanotube fabric spans the gap and has a longitudinal extent that is slightly longer than the defined width of the gap. Under certain embodiments, a clamp is disposed at each of two ends of the nanotube fabric segment and disposed over at least a portion of the nanotube fabric segment substantially at the edges defining the gap. Under certain embodiments, the clamp is made of electrically-conductive material. Under certain embodiments, the contact between the nanotube patch and the trace is a non-volatile state. Under certain embodiments, the contact between the nanotube patch and the trace is a volatile state. Under certain embodiments, the at least one electrically conductive trace has an interface material to alter the attractive force between the nanotube fabric segment and the electrically conductive trace.

    摘要： Non-volatile field effect devices and circuits using same. A non-volatile field effect device includes a source, drain and gate with a field-modulatable channel between the source and drain. Each of the source, drain, and gate have a corresponding terminal. An electromechanically-deflectable, nanotube switching element is electrically positioned between one of the source, drain and gate and its corresponding terminal. The others of the source, drain and gate are directly connected to their corresponding terminals. The nanotube switching element is electromechanically-deflectable in response to electrical stimulation at two control terminals to create one of a non-volatile open and non-volatile closed electrical communication state between the one of the source, drain and gate and its corresponding terminal. Under one embodiment, one of the two control terminals has a dielectric surface for contact with the nanotube switching element when creating a non-volatile open state. Under one embodiment, the source, drain and gate may be stimulated at any voltage level from ground to supply voltage, and wherein the two control terminals are stimulated at any voltage level from ground to a switching threshold voltage larger in magnitude than the supply voltage. Under one embodiment, the nanotube switching element includes an article made from nanofabric that is positioned between the two control terminals. Under one embodiment, one of the two control terminals is a release electrode for electrostatically pulling the nanotube article out of contact with the one of the source, drain and gate so as to form a non-volatile open state. Under one embodiment, the other of the two control terminals is a set electrode for electrostatically pulling the nanotube article into contact with the one of the source, drain and gate so as to form a non-volatile closed state.

    摘要： Electro-mechanical switches and memory cells using vertically-disposed nanofabric articles and methods of making the same are described. An electro-mechanical device, includes a structure having a major horizontal surface and a channel formed therein. A conductive trace is in the channel; and a nanotube article vertically suspended in the channel, in spaced relation to a vertical wall of the channel. The article is electro-mechanically deflectable in a horizontal direction toward the conductive trace. Under certain embodiments, the vertically suspended extent of the nanotube article is defined by a thin film process. Under certain embodiments, the vertically suspended extent of the nanotube article is about 50 nanometers or less. Under certain embodiments, the nanotube article is clamped with a conducting material disposed in porous spaces between some nanotubes of the nanotube article. Under certain embodiments, the nanotube article is formed from a porous nanofabric. Under certain embodiments, the nanotube article is electromechanically deflectable into contact with the conductive trace and the contact is either a volatile state or non-volatile state depending on the device construction. Under certain embodiments, the vertically oriented device is arranged into various forms of three-trace devices. Under certain embodiments, the channel may be used for multiple independent devices, or for devices that share a common electrode.
