My Research

Nicholas J. Borys, Ph.D

I am an experimental physicist and materials scientist at the Molecular Foundry at Lawrence Berkeley National Lab. My expertise is in condensed matter physics with an emphasis on the interactions between light and nanoscale materials where ultra-small physical dimensions enhance quantum mechanical phenomena. The overarching goal of my research is to develop novel quantum materials and optics-based measurement techniques for next-generation solar energy harvesting, efficient lighting, advanced computing and information technologies. For more information on my research please see my publications and the media coverage of my scientific work.
