Transition metal dichalcogenides (TMDs) exhibit fascinating physical properties, e.g., high carrier mobility, tunable energy band structure, wide spectral response and mechanical flexibility, depending on number of the van der Waals layer. In this talk, I present synthesis, post-synthetic treatments, and applications of multilayered TMDs. First, a couple of opto-electronic applications are shown in terms of flexible, transparent, and photo-sensing devices, in which multilayered molybdenum disulfides or molybdenum diselenides used as active components of thin-film transistors. Next, chemical vapor deposition (CVD) technique is presented especially for synthesizing multilayered TMDs, and pros and cons are discussed including defect-related variation of the optical properties. Finally, hybridizations between multilayered TMDs and organic small molecules/polymers are introduced as a post-synthetic strategy for modifying their physical properties as well as device performances. |
