The Electrodeposition of High-Density, Ordered Arrays of Bi1-xSbx Nanowires

2 páginas, 3 figuras.Here we report the synthesis of dense arrays of Bi1-xSbx nanowires with >5 × 1010 nanowires/cm2. The individual wires are crystalline, relatively homogeneous, and highly textured in a 110 direction, with diameters of 40 nm and a composition of x = 12−15 atom % Sb. By tuning the solution concentrations and controlling the growth rate by controlling the potential, the composition, crystallinity, and morphology of the nanowires can be varied.Funding was provided by the Office of Naval Research (ONR N00014-01-1-1058) and the Department of Defense ONR-MURI on Thermoelectrics (N00014-97-1-0516).
