Bridging the Gap: Layered Black Phosphorus for Electronics and Optoelectronics
Black phosphorus recently emerged as a promising new 2D material due to its widely tunable and direct bandgap, high carrier mobility and remarkable in-plane anisotropic electrical, optical and phonon properties. It serendipitously bridges the zero-gap graphene and the relatively large-bandgap transition metal dichalcogenides such as molybdenum disulfide (MoS2). In this talk, I will first cover the basic properties of few-layer and thin-film black phosphorus, followed by a discussion of recent observation of highly anisotropic robust excitons in monolayer black phosphorus. Finally I will present a few potential applications of black phosphorus such as radio-frequency transistors and wideband photodetectors.

Biography: Fengnian Xia received the B.S. degree with highest honor in electronics engineering from Tsinghua University, Beijing, China, in 1998 and M.A. and Ph.D. degrees in electrical engineering from Princeton University, Princeton, NJ, USA in 2001 and 2005, respectively. He joined IBM Thomas J. Watson research center in Yorktown Heights, NY, USA as a postdoc in March 2005, and was a Research Staff Member before he started at Yale University as an assistant professor in September 2013. His current research focuses on nanophotonics and nanoelectronics using emerging materials such as graphene, transition metal dichalcogenides, and black phosphorus. He is also actively pursuing carrier transport and light-matter interaction research in dimensional systems.

He received an IBM corporate award, three IBM research division level awards, and numerous IBM invention achievement awards. In 2011, Dr. Xia was selected by MIT technology review magazine as a top young innovator under the age of 35. He received the 2015 Young Investigator Award from the Office of Naval Research (ONR-YIP).
