A Novel Method for Preparing Copper Nanorods and Nanowires

Vacuum vapor deposition of copper nanorods and nanowires (see Figure) is reported. This novel one‐step procedure involves copper vapor generation and redeposition on a substrate under very low pressure or vacuum conditions. Nanorods and nanowires of a variety of materials apart from copper, e.g., other metals, alloys, and semiconductors, can also be synthesized using this method.
