Zou, Yichao and Chen, Zhi-Gang and Huang, Yang and Zou, Jin and Drennan, John (2014) Au-catalyzed and catalyst-free growth of one-dimensional Bi2Se3 nanostructures. In: 2014 Conference on Optoelectronic and Microelectronic Materials and Devices (COMMAD 2014), 14-17 Dec 2014, Perth, Australia.


Bi2Se3 nanoribbons and nanowires were synthesized by Au-catalyzed and catalyst-free chemical vapor deposition methods. The growth of Au-catalyzed Bi2Se3 nanoribbons and nanowires is governed by the vapor-solid-solid mechanism, and the nanoribbons grow along <1120> and the nanowires grow along <0001> directions. Catalyst-free grown Bi2Se3 nanoribbons are found to have a growth direction of <1120> and their growth is induced by a Se-catalyzed vapor-liquid-solid mechanism.
