报告摘要：

Two-dimensional (2D) materials have become very important building blocks for electronic, photonic, and phononic devices. Owing to the strong quantum confinements and defect-free surfaces, these atomically thin layers have offered us perfect platforms to investigate the interactions among photons, electrons and phonons. The unique interactions in these 2D materials are very important for both scientific research and application engineering. In this talk, I would like to briefly summarize the key findings, opportunities and challenges in this field. Next, I will highlight our recent research achievements - the demonstrations of strong light-matter interactions in 2D materials for future nano-photonic devices. In particular, we demonstrated atomically thin micro-lens using 2D MoS2, the thinnest optical component around the world, which are based on the strong elastic light-matter interactions in high-index 2D materials. Also, I would like to show the extraordinary inelastic light-matter interactions in 2D materials, taking the recently emerged phosphorene as an example. Phosphorene owns quasi-1D excitons in a 2D system. Also, we are able to precisely engineer the 0D-like excitons in air-stable monolayer phosphorene, which provides a unique platform to investigate the fundamental phenomena in the ideal 2D-1D-0D hybrid system. Finally, I will briefly talk about my vision and discuss our future directions.
