Cody’s work on “Characterization of porosity in periodic 3D nanostructures using spectroscopic scatterometry” was published in the Journal of Vacuum Science and Technology B. Congratulations!

Chang Group attends the 66th International Conference on Electron, Ion, and Photon Beam Technology and Nanofabrication (EIPBN) in San Francisco, CA. The group presented talks on Antireflection sapphire nanostructures by Jeffrey, Anti-dust nanostructures by Andrew, Multilayer nanolattices by Vijay and Metrology of periodic 3D nanostructures by Cody. The group also presented posters on EUV colloidal lithography by Saurav, Metrology of Direct Write Laser Ablation using OES by Briana and Fabrication of nanostructures using colloidal nanosphere assembly by Ethan. In addition, Saurav also participated in the EIPBN startup contest where he presented a poster and made an elevator pitch on Fabrication of ultra-low refractive index nano-lattice material and Dr. Chih-Hao Chang served as the program chair of the conference. Congratulations everybody!

Briana and Rachel have finished their undergraduate journey and graduated with their BS degrees! Both have been Undergraduate Research Assistants with the group since 2021, and will be dearly missed! They will continue their graduate studies to pursue PhD degrees, Briana at MIT and Rachel at Georgia Tech. We are proud of what you have accomplished in our group and look forward to your future contributions to engineering and science!

Briana has been selected as a recipient of the prestigious NSF Graduate Research Fellowship Program (GRFP)! Congratulations!

Congratulations to Saurav for completing the NSF National Innovation Corps Teams program! The goal of the program is to support innovators in developing technologies with commercial potential and help move their ideas from the lab to the marketplace. Read about the work from Team 3D Nanotech!

Sam’s journal paper “Engineering Large-Area Antidust Surfaces by Harnessing Interparticle Forces“ has been published in the journal ACS Applied Materials & Interfaces.
