Self-assembled nanoparticle spirals from two-dimensional compositional banding in thin films

Venkatachalam, Dinesh K.; Fletcher, Neville H.; Sood, Dinesh K.; Elliman, Robert G.


A self-assembly process is reported in which spiral patterns of goldnanoparticles form on siliconsurfaces during the epitaxial crystallization of thin gold-silicon alloy layers. This behavior is observed only for gold concentrations above a critical value and is shown to result from two-dimensional compositional banding of a liquid alloy layer during the crystallization process. The compositional banding consists of alternate gold-rich and silicon-rich alloy bands, which are shown to be a...[Show more]
