Transition metal dichalcogenides (TMDs) have attracted tremendous attention due to their unique optical and electronic properties, which arise from their layer-dependent electrical and optical characteristics. In particular, the chemical vapor deposition (CVD) growth technique has provided an opportunity for TMDs to advance their use in large-scale device applications. The modulation of optical and electrical properties of TMDCs is important for enabling various devices. Therefore, it is crucial to develop a strategy for implementing high-performance devices. Recently, reports have emerged on the modulation of the optical and electrical properties of TMDCs through doping, strain, contact engineering, and 2D material-based heterostructures. Additionally, an understanding of the exciton dynamics in TMDs is considered important for fabricating and utilizing them in device structures.

In this talk, I will introduce the modulated optical and electrical properties based on 2D Materials achieved by engineering the surface. This talk mainly focuses on studying the complex exciton behavior on 2D Materials.
