Joseph B. Herzog is an Assistant professor in the Department of Physics at the University of Arkansas who also serves as a faculty in the Microelectronics-Photonics Program and the Institute for Nanoscience and Engineering. He received his PhD from the University of Notre Dame working in the Nano-Optics Research Lab with J. Merz and A. Mintairov. After this he was a Welch Postdoctoral Research Associate, researching plasmonic nanostructures at Rice University with Douglas Natelson in the Department of Physics & Astronomy. In the summer of 2017 he was a Fellow at the U.S. Naval Research Laboratory (NRL) in Washington, DC working with Jake Fontana on tunable subnanometer gap plasmonic metasurfaces as part of the in the Office of Naval Research Summer Faculty Research Program. At the NRL he worked in the Center for Biomolecular Science and Engineering, which is a division of the Materials Directorate at the NRL. His experience also includes working for Intel Corporation both in Hillsboro, OR and Santa Clara, CA; and he worked at the Berliner Elektronenspeicherring-Gesellschaft für Synchrotronstrahlung m.b.H. (BESSY - Berlin electron storage ring company for synchrotron radiation) in Berlin, Germany, researching ultra thick high-aspect-ratio microfabrication. His research focuses on experimental nano-optics, including plasmonics, nanofabrication, computational modeling, and photonic crystals.

Current Research Projects
The Herzog Lab research program specializes in the following areas:
Nano-Fabrication: Researcher in group fabricate metal nanostructures with features that can be smaller than structures fabricated with the more-common electron beam lithography (EBL) technique. Typically the smallest feature with EBL alone can reach about 40 nm. In our lab we use EBL combined with a recently developed self-aligned technique which can make truly nanoscale features than can be less than 10 nm. Read more...
Computational Electromagnetics: Modeling optics (electromagnetic waves) with a finite element method has proven to be extremely accurate. We use this tool to help design and analyze plasmonic nanostructure. Recent developments in computational performance enables complex and robust calculations and modeling. Research in the area involves 3D designs and studies, and use of high performance super computing. Read more...
Spectroscopic Optical Characterization: Once fabricated, our group measures the optical properties of the plasmonic nanostructures with various spectroscopic techniques in order to confirm our design and build towards more useful and efficient structures. Optical characterization techniques include Dark-field spectroscopy, Raman spectroscopy, and Photoluminescence experiments. Read more...
Photonic Crystal Nanostructures: Our group studies the optical properties of photonic crystal (PC) structures. PCs are periodic structures that can reflect or guide light very efficiently. This work, in collaboration with A. Alverson, studies diatoms which have a natural nanostructures in their shells (or frustules). Additionally, group members study the optical properties of other recently-developed PC fabrication techniques. Read more...
