BeiBei Zeng is a Doctoral candidate in Electrical Engineering and an Innovator in Nanoplasmonics

Beibei Zeng is a graduate student in Prof. Fil Bartoli's group, and a student member of the Center for Photonics and Nanoelectronics. His current research interests include nanophotonics, plasmonics, nanofabrication, and their applications in photovoltaics, displays, and biosensors. During the past four years, he spent much of his time investigating the extraordinary properties of Surface plasmon resonances (SPRs) in ultrathin nanopatterned metal films. SPRs are collective charge density oscillations induced by an electric field, and can enhance and confine the electromagnetic field within nanoscale dimensions from the metal surface. As the thickness of metal film decreases to be comparable to its skin depth (optically-thin), two single-interface SPRs on the top and bottom metal surfaces combine to form coupled SPRs, which exhibit extraordinary optical phenomena. He has explored the potential of SPRs in ultrathin nanopatterned metal films for different practical applications, achieving superior performances compared with their optically-thick counterparts in plasmonic-enhanced photovoltaics, color filters and biosensing. In his research, he has made major contributions in these areas by elucidating underlying physical mechanisms of SPRs in ultrathin nanostructured metals and tailoring them for different niche applications.

Beibei has published articles in internationally renowned journals such as Nature: Scientific Reports, Journal Applied Physics, Lab on a chip, and Optical Communications, and his work has been widely reported in different media. He has presented his research in invited seminars at the Zhejiang University's Department of Electrical Engineering, China, and the Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences in 2014. Beibei holds a number of patents, and has also served as an active reviewer for over 15 leading journals, including Nature: Scientific Reports, Applied Physics Letters, Optics Express, Optics Letters, Applied Optics, JOSA A, Organic Electronics, Nanotechnology, IEEE JSTQE, IEEE Photonics Journal, IEEE PTL, Journal of Physics D, etc.

He earned a B.S. in mechanical science and engineering in 2007 from Jilin University, one of the top science and engineering schools in China, where he was awarded various prizes and scholarships for excellent academic performance. From Jilin Univ., he went to Chengdu, where he earned a master's degree in 2010 from the Chinese Academy of Sciences' Institute of Optics and Electronics.

In Beibei's most recent article, which was coauthored by Professor Bartoli and published by Scientific Reports, a publication of the Nature group, he reported that the ultrathin  nanostructured metals have more than doubled the transmission efficiency of plasmonic color filters, indicating a greater potential role for plasmonics in future display technologies. While currently exploring applications of this work, he is also investigating novel nanoplasmonic structures to probe biological cells and biomolecules, for applications in biosensing and biomedicine.
