WebDec 9, 2024 · The construction of two-dimensional (2D) transition-metal dichalcogenide (TMDC) alloy-based vertical heterostructures can provide an alternative candidate for developing ultrathin and novel optoelectronic devices. WebJun 28, 2024 · In an earlier study, also published in the journal Advanced Materials in 2024, the group had shown that two-metal TMDC alloys showed improved catalytic activity over … Transition-metal dichalcogenide (TMD or TMDC) monolayers are atomically thin semiconductors of the type MX2, 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 their extraordinary thinness. For example, a MoS2 mo… rn ios 打包
