    摘要: Methods for forming anisotropic nanotube fabrics are disclosed. In one aspect, a nanotube application solution is rendered into a nematic state prior to its application over a substrate. In another aspect, a pump and narrow nozzle assembly are employed to realize a flow induced alignment of a plurality of individual nanotube elements as they are deposited onto a substrate element. In another aspect, nanotube adhesion promoter materials are used to form a patterned nanotube application layer, providing narrow channels over which nanotube elements will self align during an application process. Specific dip coating processes which are well suited for aiding in the creation of anisotropic nanotube fabrics are also disclosed.

    摘要: Methods for passivating a carbonic nanolayer (that is, material layers comprised of low dimensional carbon structures with delocalized electrons such as carbon nanotubes and nano-scopic graphene flecks) to prevent or otherwise limit the encroachment of another material layer are disclosed. In some embodiments, a sacrificial material is implanted within a porous carbonic nanolayer to fill in the voids within the porous carbonic nanolayer while one or more other material layers are applied over or alongside the carbonic nanolayer. Once the other material layers are in place, the sacrificial material is removed. In other embodiments, a non-sacrificial filler material (selected and deposited in such a way as to not impair the switching function of the carbonic nanolayer) is used to form a barrier layer within a carbonic nanolayer. In other embodiments, carbon structures are combined with and nanoscopic particles to limit the porosity of a carbonic nanolayer.

    摘要: Under one aspect, a memory array includes word lines; bit lines; memory cells; and a memory operation circuit. Each memory cell responds to electrical stimulus on a word line and on a bit line and includes: a two-terminal non-volatile nanotube switching device having first and second terminals, a semiconductor diode element, and a nanotube fabric article capable of multiple resistance states. The semiconductor diode and nanotube article are between and in electrical communication with the first and second terminals, which are coupled to the word line bit line respectively. The operation circuit selects cells by activating bit and/or word lines, detects a resistance state of the nanotube fabric article of a selected memory cell, and adjusts electrical stimulus applied to the cell to controllably induce a selected resistance state in the nanotube fabric article. The selected resistance state corresponds to an informational state of the memory cell.

    摘要: The present invention is directed to structures and methods of fabricating electromechanical memory cells having nanotube crossbar elements. Such memory cells include a substrate having transistor with a contact that electrically contacts with the transistor. A first support layer is formed over the substrate with an opening that defines a lower chamber above the electrical contact. A nanotube crossbar element is arranged to span the lower chamber. A second support layer is formed with an opening that defines a top chamber above the lower chamber, the top chamber including an extension region that extends beyond an edge of the lower chamber to expose a portion of the top surface of the first support layer. A roof layer covers the top of the top chamber and includes an aperture that exposes a portion of the extension region of the top chamber and includes a plug that extends into the aperture in the roof layer to seal the top and bottom chambers. The memory cell further includes an electrode that overlies the crossbar element such that electrical signals can activate the electrode to attract or repel the crossbar element to set a memory state for the transistor.
