Gold Core-Semiconductor Shell Nanowires Prepared by Lithographically Patterned Nanowire Electrodeposition

摘要

Here, we report the synthesis of Au/PbSe and Au/copper indium diselenide (CIS) core/shell nanowires. The nanowires were synthesized by the aqueous electrodeposition of either PbSe or CIS onto gold nanowires prepared by lithographically patterned nanowire electrodeposition. The resulting nanowires are nanocrystalline, exhibit a sharp boundary between the gold core and the semiconducting coating, and are photoconductive, with enhanced light absorption in smaller nanowires.
