  • Publication number: 20120085991
    Abstract: The present disclosure provides a semiconductor structure including a nanoribbon-containing layer of alternating graphene nanoribbons separated by alternating insulating ribbons. The alternating graphene nanoribbons are parallel to a surface of an underlying substrate and, in some embodiments, might be oriented along crystallographic directions of the substrate. The alternating insulating ribbons may comprise hydrogenated graphene, i.e., graphane, fluorinated graphene, or fluorographene. The semiconductor structure mentioned above can be formed by selectively converting portions of an initial graphene layer into alternating insulating ribbons, while the non-converted portions of the initial graphene form the alternating graphene nanoribbons. Semiconductor devices such as, for example, field effect transistors, can be formed atop the semiconductor structure provided in the present disclosure.

  • Publication number: 20120088934
    Abstract: Disclosed herein is a sequential functionalization methodology for the covalent modification of nanotubes with between one and four repeat units of a polymer. Covalent attachment of oligomer units to the surface of nanotubes results in oligomer units forming an organic sheath around the nanotubes, polymer-functionalized-nanotubes (P-NTs). P-NTs possess chemical functionality identical to that of the functionalizing polymer, and thus provide nanoscale scaffolds which may be readily dispersed within a monomer solution and participate in the polymerization reaction to form a polymer-nanotube/polymer composite. Formation of polymer in the presence of P-NTs leads to a uniform dispersion of nanotubes within the polymer matrix, in contrast to aggregated masses of nanotubes in the case of pristine-NTs.

  • Publication number: 20120032550
    Abstract: The invention relates to the electric connection of conductor ends (26b), which are arranged in pairs and are positioned on top of each other, of a winding comprising individual conductors and to a method for establishing the connection, wherein a plurality of the conductor ends in pairs are arranged next to each other at a distance (a). In order to establish the electric connection with the briefest and most spatially delimited heating possible, it is proposed to insert a nanofoil (30) between the conductor ends (26b) that are to be connected in pairs, to then press the conductor ends together to clamp the nanofoil (30), and to finally weld or solder the conductor ends to each other by igniting the nanofoil (30).
