    摘要: A method for selectively assembling a molecular device on a substrate comprises contacting the first substrate with a solution containing molecular devices; impeding bonding of the molecular devices to the substrate such that application of a voltage potential to the substrate results in assembly of the molecular device on the substrate at a rate that is at least 1.5 times the rate of assembly of the molecular device on a voltage-neutral substrate; and applying a voltage potential to the substrate so as to cause the molecular devices to assemble on the substrate. A nanoscale computing device is described that includes a substrate, a pair of conductive input/output electrodes carried on this substrate and disposed in spaced-apart relationship and a substantially disordered assembly of nanowires formed on the substrate in a region between the electrodes, thereby forming at least one programmable conductive pathway between the pair of electrodes.

    摘要: An assembly of a NanoCell comprising a disordered array of metallic islands interlinked with molecules between metallic input/output leads and with disordered arrays of molecules and Au islands is disclosed. The NanoCell may function both as a memory device that is programmable post-fabrication. The assembled NanoCells exhibit reproducible switching behavior and at least two types of memory effects at room temperature. The switch-type memory is characteristic of a destructive read while the conductivity-type memory features a nondestructive read. Both types of s memory effects are stable for more than a week at room temperature and bit level ratios (0:1) of the conductivity-type memory have been observed to be as high as 104:1 and reaching 106:1 upon ozone treatment which likely destroys extraneous leakage pathways. The invention demonstrates the efficacy of a disordered

    摘要: The invention incorporates new processes for the chemical modification of carbon nanotubes. Such processes involve the derivatization of multi- and single-wall carbon nanotubes, including small diameter (ca. 0.7 nm) single-wall carbon nanotubes, with diazonium species. The method allows the chemical attachment of a variety of organic compounds to the side and ends of carbon nanotubes. These chemically modified nanotubes have applications in polymer composite materials, molecular electronic applications, and sensor devices. The methods of derivatization include electrochemical induced reactions, thermally induced reactions (via in-situ generation of diazonium compounds or pre-formed diazonium compounds), and photochemically induced reactions. The derivatization causes significant changes in the spectroscopic properties of the nanotubes. The estimated degree of functionality is ca. 1 out of every 20 to 30 carbons in a nanotube bearing a functionality moiety. Such electrochemical reduction processes can be adapted to apply site-selective chemical functionalization of nanotubes. Moreover, when modified with suitable chemical groups, the derivatized nanotubes are chemically compatible with a polymer matrix, allowing transfer of the properties of the nanotubes (such as, mechanical strength or electrical conductivity) to the properties of the composite material as a whole. Furthermore, when modified with suitable chemical groups, the groups can be polymerized to form a polymer that includes carbon nanotubes.

    摘要: The present invention is directed towards methods of thermally defunctionalizing functionalized (derivatized) carbon nanotubes (CNTs) in solution or suspended in a liquid medium. Such defunctionalization largely comprises the removal of sidewall functionality from the CNTs, but can also serve to remove functionality from the CNT ends. Such methods facilitate the resuspension of such defunctionalized CNTs in various solvents and permit the defunctionalization of functionalized CNTs that would normally decompose (or partially decompose) upon thermal treatment. Such methods of defunctionalization can typically lead to defunctionalized CNTs that are essentially pristine (or nearly pristine), and which, in contrast to prior art methods of thermal defunctionalization, can be easily resuspended in a variety of solvents.
