Nonlinear Optics on 2D Layered Structures.

Van der Walls layered structures, primarily graphene and beyond-graphene 2D crystals, such as transitional metal dichalcogenides (TMDs) and black phosphorus, have recently attracted immense interest due to their unique physical properties and potential application in electronics, optoelectronics, and energy harvesting. Recently, nonlinear optical responses (or ultrafast electronic and structural responses) in 2D layered structures have gained great interest. Our goal is to control preparation of various kinds of high-quality 2D layered structures and develop multimodal nonlinear optical imaging methods to characterize their critical properties, including crystal orientation, chemical dynamics, and ultrafast dynamics. This method has the advantages of versatility, high fidelity, easy operation, and fast imaging, paving the way for comprehensive characterization of van der Waals layered structures for fundamental research and practical applications.
