2D Materials: Synthesis, Catalysis, and Photonics

Monday, November 18, 2013 - 12:00pm
Linyou Cao, NCSU

Two-dimensional (2D) transition metal chalcogenide (TMDC) materials with a monolayer or few-layer of atoms have been emerging as the cutting edge of physical science and engineering.  These materials may open up new opportunities for a variety of fields, including surface science, catalysis, semiconductor technology, energy conversion, and flexible devices.

In this talk, I will first introduce the controlled scalable synthesis that we have recently developed for the growth of centimeter-scale, high quality, and uniform monolayer and fewlayer MoS2 films.  These films with atomically defined physical features provide an unprecedented platform for us to study the fundamentals in catalysis and photonics. To illustrate this notion, I will show our recent results in the layer-dependent catalytic activities and exciton dynamics of MoS2 films.

Biography: Dr. Linyou Cao is an assistant professor of Materials Science and Engineering at North Carolina State University.  He received his PhD degree in the Department of Materials Science and Engineering at Stanford in 2010, and held a Miller Research Fellowship at the University of California, Berkeley prior to joining the faculty of NCSU August  2011.  His group works on the catalysis and photonics of two-dimensional (2D) materials as well as dielectric metamaterials. Dr. Cao received a Ralph E. Powe Junior Faculty Enhancement Award from the Oak Ridge Associated Universities in 2012 and a Young Investigator Award from the Army Research Office in 2013.
