摘要： Nanotube-based switching elements with multiple controls and circuits made from such. A switching element includes an input node, an output node, and a nanotube channel element having at least one electrically conductive nanotube. A control structure is disposed in relation to the nanotube channel element to controllably form and unform an electrically conductive channel between said input node and said output node. The output node is constructed and arranged so that channel formation is substantially unaffected by the electrical state of the output node. The control structure includes a control electrode and a release electrode, disposed on opposite sides of the nanotube channel element. The control and release may be used to form a differential input, or if the device is constructed appropriately to operate the circuit in a non-volatile manner.

摘要： Field effect devices having a gate controlled via a nanotube switching element. Under one embodiment, a non-volatile transistor device includes a source region and a drain region of a first semiconductor type of material and each in electrical communication with a respective terminal. A channel region of a second semiconductor type of material is disposed between the source and drain region. A gate structure is disposed over an insulator over the channel region and has a corresponding terminal. A nanotube switching element is responsive to a first control terminal and a second control terminal and is electrically positioned in series between the gate structure and the terminal corresponding to the gate structure. The nanotube switching element is electromechanically operable to one of an open and closed state to thereby open or close an electrical communication path between the gate structure and its corresponding terminal. When the nanotube switching element is in the closed state, the channel conductivity and operation of the device is responsive to electrical stimulus at the terminals corresponding to the source and drain regions and the gate structure.

摘要： Random access memory including nanotube switching elements. A memory cell includes first and second nanotube switching elements and an electronic memory. Each nanotube switching element includes conductive terminals, a nanotube article and control circuitry capable of controllably form and unform an electrically conductive channel between the conductive terminals. The electronic memory is a volatile storage device capable of storing a logic state in response to electrical stimulus. In certain embodiment the electronic memory has cross-coupled first and second inverters in electrical communication with the first and second nanotube switching elements. The cell can operate as a normal electronic memory, or can operate in a shadow memory or store mode (e.g., when power is interrupted) to transfer the electronic memory state to the nanotube switching elements. The device may later be operated in a recall mode where the state of the nanotube switching elements may be transferred to the electronic memory.

摘要： Nanowire articles and methods of making the same are disclosed. 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.
