  • Publication number: 20200269323
    Abstract: Provided are methods for synthesizing metal nanowires in solution using an organic reducing agent. A reaction mixture can be provided in solution with a metal salt, the organic reducing agent, and a solvent, where the solvent includes a surface ligand or consists of a surface ligand. The organic reducing agent, such as benzoin, can be decomposed in the reaction mixture to form organic free radicals that reduce metal ions of the metal salt into metal. The surface ligand of the solvent can coordinate with the metal in a manner so that metal nanowires are formed in solution. The diameter and morphology of the nanowires, reaction speed, reaction yield, and other features may be tunable by adjusting parameters such as reaction temperature and chemistry of the reducing agent.

  • Patent number: 9881999
    Abstract: 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).
