One-dimensional nanostructures having uniform diameters of less than approximately 200 nm. These inventive nanostructures, which we refer to as 'nanowires', include single-crystalline homostructures as well as heterostructures of at least two single-crystalline materials having different chemical compositions. Because single-crystalline materials are used to form the heterostructure, the resultant heterostructure will be single-crystalline as well. The nanowire heterostructures are generally based on a semiconducting wire wherein the doping and composition are controlled in either the longitudinal or radial directions, or in both directions, to yield a wire that comprises different materials. Examples of resulting nanowire heterostructures include a longitudinal heterostructure nanowire (LOHN) and a coaxial heterostructure nanowire (COHN).

A nanowire switching device and method. The device has a nanowire structure comprising an elongated member having a cross-sectional area ranging from about 1 nanometers but less than about 500 nanometers, but can also be at other dimensions, which vary or are substantially constant or any combination of these. The device also has a first terminal coupled to a first portion of the nanowire structure; and a second terminal coupled to a second portion of the nanowire structure. The second portion of the nanowire structure is disposed spatially from the first portion of the nanowire structure. An active surface structure is coupled to the nanowire structure. The active surface structure extends from the first portion to the second portion along the elongated member.

Methods for electroless deposition of conductive material on a substrate using in both cases a stamp having a patterned surface which is pressed onto the surface of a substrate for printing the substrate and providing a pattern of a catalyst on the substrate on which metal deposition occurs in the course of electroless deposition by immersing the printed substrate in a plating bath are provided. In one case, the stamp is pretreated to render the pattern of the stamp wettable with a catalytic ink which is transformed to the surface of the substrate. In the other case, a catalytic layer is provided on the surface of the substrate which is patterned by the stamp transferring a resist material onto the catalytic layer so that a subsequent etching process lays open the desired pattern of the catalytic layer for electroless deposition.
