Narrow Bi2Te3 nanowire arrays, where the individual wires are dense and parallel, have been fabricated by electrodeposition. The array–template composites have a high wire density over a large area (see Figure) and are relatively thick, which makes them ideally suited for direct incorporation into existing device structures for thermoelectric or other applications.
