WebTransition-metal dichalcogenide ( TMD or TMDC) monolayers are atomically thin semiconductors of the type MX 2, with M a transition-metal atom ( Mo, W, etc.) and X a chalcogen atom ( S, Se, or Te ). One layer of M atoms is sandwiched between two layers of X atoms. They are part of the large family of so-called 2D materials, named so to emphasize … WebApr 22, 2024 · The typical structure of these Janus TMDCs is shown in figure 1(a), where the transition metal layer is sandwiched by two different chalcogen layers. The structural symmetry along the out-of-plane direction is therefore broken, leading to the different electronic, optical, and photocatalytic performances which can distinguish Janus …
