2D TMDC Materials and Heterostructures:Towards The Age of Atomic-scale Photonics（2）

2014中国国际石墨烯创新大会（Grap-China 2014）——Two-dimensional (2D) transition metal chalcogenide (TMDC) materials have been emerging as one central topic of the entire physical science and engineering.These materials show remarkable excitonic properties and offer a tantalizing prospect of scaling all kinds of semiconductor photonic devices down to a truly atomic scale! These include photodetectors, solar cells, LEDs,lasers, and optical modulators.In this talk, I will first introduce a unique self-limiting chemical vapor deposition process that my groups has recently developed for the synthesis of high-quality centimeter-scale 2D MoS2 with controlled layer numbers. I will then demonstrate a unique surface energy-assisted transfer process developed in my group that can perfectly transfer the synthesized centimeter-scale films onto arbitrary substrates with no observable wrinkles and damages.These capabilities of controlled scalable synthesis and transfer open up enormous unexplored opportunities for fundamental and applied research.
