Abstract:Two-dimensional (2D) materials, with layered van der Waals structures and atomically-thin thickness, offer a unique platform for investigating light-matter interactions. In this talk, I will first overview our previous works on light-matter interactions in layered black phosphorus and its application in optoelectronics [1-2]. Then I willfocus on our recent two representative works on light-matter interactions in 2D materials. First, I will show that light-matter interactions can provide a convenient  approach to investigate the antiferromagnetic properties of micrometer-size atomically-thin semiconducting materials, which is not accessible by the conventional approach [3]. Then, we offer an effective optical method to probe the layer-dependent mechanical properties. Combining the theoretical model, we are able to resolve the interlayer shear deformation in black phosphorus layer by layer, and extract its key thermal and mechanical parameters [4]. 

Keywords:Two-dimensional materials; Light-matter interactions; Antiferromagnetism; Strain.
