    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. The switching elements may be arranged into logic circuits and latches having differential inputs and/or non-volatile behavior.

    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.

A non-volatile transistor device includes a source region and a drain region of a first semiconductor type of material and a channel region of a second semiconductor type of material disposed between the source and drain region. A gate structure is made of at least one of semiconductive or conductive material and is disposed over an insulator over the channel region. A control gate is made of at least one of semiconductive or conductive material.

The device has a network of inherent capacitances, including an inherent capacitance of an undeflected nanotube switching element in relation to the gate structure. The network is such that the nanotube switching element is deflectable into contact with the other of the gate structure and the control gate structure in response to signals being applied to the control gate and one of the source region and drain region. Certain embodiments of the device have an area of about 4 F2. Other embodiments include a release line is positioned in spaced relation to the nanotube switching element, and having a horizontal orientation that is parallel to the orientation of the source and drain diffusions. Other embodiments provide an n2 crossbar array having n2 non-volatile transistor devices, but require only 2n control lines.
