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!
