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

Deliquescent Chromism of Nickel(II) Iodide Thin Films


In a recent collaboration paper, Tim Siegler, Mokshin Suri, and Michael Abney, alongside a team of collaborators from the Milliron Group lead by Lauren Reimnitz, observed and studied a new phase change in thin films of nickel iodide. Showing that water vapor uptake could reversibly convert NiI2 films of under 10 microns in thickness from a dark brown to an optically clear state, we demonstrated how nickel iodide thin films in ambient humidity have potential application in thermochromic smart window materials with color neutral transitions. This unique approach turns a problem common to many transition metal halides - humidity instability - into a feature, taking advantage of the color change of this degradation process. Find the paper, recently published in Langmuir, at this link.
