Experimental and theoretical methods elucidate growth mechanisms.

Potential extension to other inorganic nanowire systems.

Abstract

The fullerene (C60) nanowires, which possess a highly unusual morphology featured by a prism-like central core and three nanobelt-like wings joined along the growth direction to give an overall Y-shaped cross section, have been studied. The experimental observation coupled with theoretical calculation have enabled us to elucidate both the role of the fullerene and of the solvent in the crystallization process, thus opening up an opportunity for the in-depth understanding of the crystal growth mechanism. More generally, the method developed in this work could be extended into understanding the growth of other inorganic nanowires that have both host and guest molecules involved in their crystal lattices.
