Deterministic one-to-one synthesis of germanium nanowires and individual gold nanoseed patterning for aligned nanowire arrays

Abstract

(Figure Presented) Several breakthroughs in nanowire synthesis are reported for germanium nanowires grown from gold nanoparticle seeds by a low-temperature chemical vapor deposition process. Conditions were optimized to observe the formation of nanowires in near-quantitative yields, and post-growth flow-alignment was used to obtain quasi-parallel nanowires that originate from well-controlled singleparticle sites (see images). © 2005 Wiley-VCH Verlag GmbH & Co.
