Nanostructures, assembling method for nanowires, and device assembled from nanowires

TLDR: In this paper, the authors proposed to provide one-dimensional nanostructures having diameters along a vertical axis wherein the diameters do not change nearly 10% or more at a section showing the maximum diameter change and the maximum diameters of less than approximately 200 nm, regarding substantially crystalline nanowire structures.

Abstract: PROBLEM TO BE SOLVED: To provide one-dimensional nanostructures having diameters along a vertical axis wherein the diameters do not change nearly 10% or more at a section showing the maximum diameter change and the maximum diameters of less than approximately 200 nm, regarding substantially crystalline nanowire structures. SOLUTION: The one-dimensional nanostructures have the uniform diameters of less than approximately 200 nm. The new nanostructures called as "nanowires" include single-crystalline homostructures as well as heterostructures of two single-crystalline materials having different chemical compositions. The resulting heterostructures similarly become single crystals since the single-crystalline materials are used for forming the heterostructures. 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 including different materials. Examples of resulting nanowire heterostructures include a longitudinal heterostructure nanowire (LOHN) and a coaxial heterostructure nanowire (COHN). COPYRIGHT: (C)2011,JPO&INPIT
