WebJul 31, 2015 · Two-dimensional transition metal dichalcogenides (TMDCs) such as molybdenum sulfide MoS 2 and tungsten sulfide WSe 2 have potential applications in electronics because they exhibit high on-off current … WebSep 9, 2024 · In this study, a color-tunable light-emitting device using compositionally graded TMDC alloys is fabricated. The monolayer WS 2 /WSe 2 alloy grown by chemical vapor deposition shows a spatial gradient in the light-emission energy, which varies from 2.1 to 1.7 eV. This alloy is incorporated in an electrolyte-based light-emitting device structure ...

WebMar 14, 2024 · Abstract We report an ab initio study of thermodynamic properties of two-dimensional transition-metal dichalcogenides (2D-TMDC) alloys, Mo (1-x) W x (S,Se,Te) 2. We compute the Helmholtz free energy as a function of alloy composition (x) and temperature, in the framework of the generalized quasi-chemical approximation (GQCA). WebJun 2, 2024 · in 2024, the group had shown that two-metal TMDC alloys showed improved catalytic activity over individual TMDCs.
