Abstract Scope |
Solid-state materials based on van der Waals (vdW) crystals continues to expand rapidly, with a rich library of compositions documented to date, that are realized through various synthesis approaches, such as vapor-growth, liquid phase exfoliation and through mechanical exfoliation. Their superb electronic, opto-electronic, and strain-dependent properties offer intriguing prospects for devices. The strong light-matter interactions in many two-dimensional layered materials (2DLMs) possessing a bandgap is largely mediated via the robust excitonic binding energy in such systems, which reveals a rich interplay of exciton-based multibody dynamics, non-linear optical features, and strain-modulated emission. Besides the individual crystallites, their pristine interfacial structural attributes also facilitate the lego-like construction of vdW heterostructures, in a single system-on-chip framework. I will discuss our recent activities on the use of inorganic 2DLMs and more complex organo-halide compositions involving the 2D perovskites for device applications ranging from radiation and strain sensors, quantum emitters, photovoltaics and flexible optoelectronics. |
