Welcome to the Korgel Research Group!

Nanotechnology is the field of applied science at the atomic and molecular scale. Our experimental group focuses on investigating size-tunable material properties, and the self-assembly and fabrication of nanostructures. This multidisciplinary research finds applications in microelectronics, photonics, photovoltaics, spintronics, coatings, sensors and biotechnology. research overview

Dr. Korgel also directs the Industry/University Cooperative Research Center (I/UCRC) on Next Generation Photovoltaics.

Sponsorship and press inquiries about the I/UCRC can be sent to jpeck@che.utexas.edu

Role of Halides in the Ordered Structure Transitions of Heated Gold Nanocrystal Superlattices

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.
