Tailored Growth of Transition Metal Dichalcogenide Monolayers: From Fundamental Nanoscience to Emerging Technologies

Two-dimensional (2D) materials, along with their van der Waals and lateral heterostructures, possess a wealth of unique electronic, optoelectronic, and photonic properties that make them highly attractive for both fundamental research and technological applications. Realizing this potential technologically requires tailored synthesis, for example by chemical vapor deposition (CVD) and metal-organic chemical vapor deposition (MOCVD), as well as a thorough understanding of the roles of intrinsic defects and 2D material–substrate interactions. In this talk, I will present an overview of our recent progress in the synthesis and characterization of 2D materials, as well as our studies of fundamental photonic and optoelectronic phenomena in various 2D material systems, including device applications. Particular focus will be placed on monolayer transition-metal dichalcogenides (TMDs), their engineered variants such as Janus TMDs and lateral heterostructures, and their integration with other low-dimensional and three-dimensional materials, including optical fibers, waveguides and photonic metasurfaces.
