"2D Transition Metal Dichalcogenide Materials: Towards Atomic-scale Photonics" Dr. Linyou Cao Assistant Professor, Department of Materials Science and Engineering & Department of Physics North Carolina State University Two-dimensional (2D) transition metal dichalcogenide (TMDC) materials such as MoS2, WS2, MoSe2, and WSe2 have recently emerged as a topical area of physical science and engineering. It has been widely believe that one of the most appealing applications of these materials is in photonics due to their semiconducting nature, perfect surface passivation, and extraordinarily strong exciton binding energies. These materials promise to open up a new age of atomic-scale photonics in which the devices would be scaled a truly atomic level to provide high performance and exotic functionalities. However, the understanding for the fundamental photophysics of 2D TMDC materials has remained limited, which stands as a major challenge for the development of the atomic-scale devices. Linyou Cao is an assistant professor in the Department of Materials Science and Engineering at North Carolina State University (NCSU). He obtained his PhD degree in materials science from Stanford University in 2010 and held a Miller Research Fellowship at the University of California, Berkeley prior to joining the faculty of NCSU in July 2011. His research work has focused on the photonics and catalysis of 2D TMDC materials.
