Abstract
We demonstrate the growth of unusual metal nanowhiskers by glancing angle deposition on a high temperature (HT-GLAD) substrate, while the usual nanocolumnar structures completely disappear due to accelerated surface diffusion. HT-GLAD is essential for the nucleation of the nanowhiskers and efficient supply of metal atoms on the side surface of the vertically growing nanowhiskers. HT-GLAD will, for the first time, reveal the mechanisms for the vapor growth of metal whiskers and be useful to produce high-quality metal nanowires for novel device elements.
