    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.

A conductive article includes a plurality of inter-contacting nanowire segments that define a plurality of conductive pathways along the article. The nanowire segments may be semiconducting nanowires, metallic nanowires, nanotubes, single walled carbon nanotubes, multi-walled carbon nanotubes, or nanowires entangled with nanotubes. The various segments may have different lengths and may include segments having a length shorter than the length of the article. A strapping material may be positioned to contact a portion of the plurality of nanowire segments. The strapping material may be patterned to create the shape of a frame with an opening that exposes an area of the nanowire fabric. Such a strapping layer may also be used for making electrical contact to the nanowire fabric especially for electrical stitching to lower the overall resistance of the fabric.
