The focus of this Letter is the electrical characterization of electrodeposited single Bi0.92Sb0.08 nanowires using alumina oxide membranes as templates. Resolution of the membranes afterwards and a suitable process for contacting single nanowires exhibit the possibility to maintain the absolute values of numerous transport measurements. The temperature dependent resistance, magnetoresistance and Seebeck coefficient of single Bi0.92Sb0.08 nanowires with a diameter between 220–350 nm is presented. Additionally the influence of an annealing process on the transport properties is investigated. It turns out that the transport properties of annealed Bi0.92Sb0.08 wires become more predictable compared to as-prepared wires.
