Structure and Thermoelectric Properties of Bi_2-xSb_xTe₃ Nanowires Grown in Flexible Nanoporous Polycarbonate Templates.

ABSTRACT: We report the room-temperature growth of vertically aligned ternary Bi_2-xSb_xTe₃ nanowires of diameter ~200 nm and length ~12 µm, within flexible track-etched nanoporous polycarbonate (PC) templates via a one-step electrodeposition process. Bi_2-xSb_xTe₃ nanowires with compositions spanning the entire range from pure Bi₂Te₃ (x = 0) to pure Sb₂Te₃ (x = 2) were systematically grown within the nanoporous channels of PC templates from a tartaric-nitric acid based electrolyte, at the end of which highly crystalline nanowires of uniform composition were obtained. Compositional analysis showed that the Sb concentration could be tuned by simply varying the electrolyte composition without any need for further anneali
