Nanowires of antimony (Sb) with diameters ranging from 90 down to 20 nm have been synthesized by electrodeposition within nanoporous polycarbonate membrane. The salient point of the present work is the detailed examination of each wire individually giving evidence of their good quality. The growth morphology, crystalline quality as well as chemical composition of individual nanowires were carried out by combination of various transmission electron microscopy (TEM) techniques. They are single crystals and have homogeneous cylindrical shape. However, a distribution of wire diameters and a roughness of few nanometers on the wire surface have been observed. Chemical analyses using electron energy loss spectroscopy (EELS) confirmed the purity of electrodeposited Sb nanowires, but revealed the existence of an oxidized layer (≤2 nm in width) surrounding the wires.
