Control of electrically and optically active structural disorder in 2D transition metal dichalcogenides

Abstract Structural disorder affects the electronic structures of 2D TMDs, offering active control of their electrical and optical properties. The control requires knowledge about the correlation between structure and properties, and also techniques for introducing and stabilizing the structural disorder. The recent significant progress shows that the tunability of the structural disorder enables new functionalities of the 2D TMDs. Here we provide an up-to-date review of the current developments.
