Role of Halides in the Ordered Structure Transitions of Heated Gold Nanocrystal Superlattices
It is known that Dodecanethiol-capped gold (Au) nanocrystal superlattices can undergo a surprisingly diverse series of ordered structure transitions when heated. In this paper Yixuan Yu, Brian Goodfellow, Michael R. Rasch and Christian Bosoy showed that in the presence of halide-containing surfactants the nanocrystals ripen at much lower temperature and superlattices undergo various ordered structure transitions upon heating. This work was done in collaboration with Dr. Smilgies at Cornell High Energy Synchrotron Source (CHESS) and was recently published in Langmuir and selected as an ACS Editors' Choice article.
