摘要： An improved switching material for forming a composite article over a substrate is disclosed. A first volume of nanotubes is combined with a second volume of nanoscopic particles in a predefined ration relative to the first volume of nanotubes to form a mixture. This mixture can then be deposited over a substrate as a relatively thick composite article via a spin coating process. The composite article may possess improved switching properties over that of a nanotube-only switching article. A method for forming substantially uniform nanoscopic particles of carbon, which contains one or more allotropes of carbon, is also disclosed.

摘要： Solutions of carbon nanotubes and methods for purifying the solutions are provided. The methods include mixing, for example, at least one complexing agents, at least one ionic species, and/or at least one buffer oxide etch (BOE) with a liquid medium containing carbon nanotubes and different types of contaminants, such as metal impurities, amorphous carbon, and/or silica particles, and performing a filtration process to the liquid medium so as to remove or reduce the contaminants in the liquid medium. As a result, carbon nanotube solutions of low contaminants are produced. In some embodiments, the solutions of this disclosure include a high concentration of carbon nanotubes and are substantially free from metal, amorphous carbon, and/or silica impurities.

摘要： Inverter circuits and NAND circuits comprising nanotube based FETs and methods of making the same are described. Such circuits can be fabricating using field effect transistors comprising a source, a drain, a channel region, and a gate, wherein the first channel region includes a fabric of semiconducting nanotubes of a given conductivity type. Such FETs can be arranged to provide inverter circuits in either two-dimension or three-dimensional (stacked) layouts. Design equations based upon consideration of the electrical characteristics of the nanotubes are described which permit optimization of circuit design layout based upon constants that are indicative of the current carrying capacity of the nanotube fabrics of different FETs.

摘要： Methods for reading and programming one or more resistive change elements within a 1-R resistive change element array are disclosed. These methods include using measurement and storage elements to measure the electrical response of one or more selected cells within an array and then comparing that stored electrical response to the electrical response of a reference element within the array to determine the resistive state of the one or more selected cells. These methods also include programming methods wherein selectable current limiting elements are used to permit or inhibit programming currents from flowing through selected and unselected cells, respectively. These methods further include programming methods that use specific biasing of array lines to provide sufficient programming currents through only selected cells.

摘要： A method for arranging nanotube elements within nanotube fabric layers and films is disclosed. A directional force is applied over a nanotube fabric layer to render the fabric layer into an ordered network of nanotube elements. That is, a network of nanotube elements drawn together along their sidewalls and substantially oriented in a uniform direction. In some embodiments this directional force is applied by rolling a cylindrical element over the fabric layer. In other embodiments this directional force is applied by passing a rubbing material over the surface of a nanotube fabric layer. In other embodiments this directional force is applied by running a polishing material over the nanotube fabric layer for a predetermined time. Exemplary rolling, rubbing, and polishing apparatuses are also disclosed.
