Title: Quaternary 2D Transition Metal Dichalcogenides (TMDs) with Tunable Bandgap [Quaternary Two-Dimensional (2D) Transition Metal Dichalcogenides (TMDs) with Tunable Bandgap]

Journal Article · · Advanced Materials

Alloying/doping in 2D material is important due to wide range bandgap tunability. Increasing the number of components would increase the degree of freedom which can provide more flexibility in tuning the bandgap and also reduces the growth temperature. Here, synthesis of quaternary alloys MoxW1–xS2ySe2(1–y) is reported using chemical vapor deposition. The composition of alloys is tuned by changing the growth temperatures. As a result, the bandgap can be tuned which varies from 1.61 to 1.85 eV. In conclusion, the detailed theoretical calculation supports the experimental observation and shows a possibility of wide tunability of bandgap.
