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

Abstract

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.
