Transition Metal Dichalcogenides
Transition-metal dichalcogenides (TMD or TMDC) are an emerging class of two-dimensional (2D) materials with the general formula MX₂, where M is a transition metal (e.g., molybdenum, tungsten) and X is a chalcogen (e.g., S, Se, or Te). MoS₂ (molybdenum disulfide) and WS₂ (tungsten disulfide) are the most well-known TMDs. Their characteristic is that even in layers only a few atoms thick, they exhibit impressive performance as semiconductors, catalysts, and sensors.
Key Properties
- 2D Structure: MoS₂ (molybdenum disulfide) and WS₂ (tungsten disulfide) exist in layers one atom thick, making them ultra-thin, flexible, and possessing a high surface area.
- Tunable Band Gap: The ....
