Bi2Te3 nanowires are of significant interest for two fields: nanostructured thermoelectrics and topological insulators. The vapor-liquid-solid method is employed in combination with annealing in a Te atmosphere, to obtain single-crystalline Bi2Te3 nanowires with reproducible electronic transport properties (electrical conductivity and Seebeck coefficient) that are close to those of intrinsic bulk Bi2Te3.
