ABSTRACT: We present the synthesis of Bi1−xSbx nanowires with controlled composition between x = 0.05 and x = 0.40 over a
wide range of diameters (20−100 nm) interesting for the investigation of the enhancement of thermoelectric efficiency via
quantum size effects. We find that the relative concentration of Bi and Sb ions in the electrolyte, together with the deposition
potential, determines the resulting nanowire composition. Morphology and composition were analyzed using X-ray diffraction,
electron microscopy, and energy dispersive X-ray analysis. Two different templates were fabricated to enable the synthesis of
nanowires with smooth and rough contour.
