The article investigates the effects of tungsten (W) doping on molybdenum disulfide (MoS2) bilayers grown via chemical vapor deposition (CVD). The incorporation of tungsten atoms into the MoS2 crystal lattice induces a structural phase transition, altering the electronic and crystallographic properties of the material. This doping-induced phase change suggests that substitutional alloying can serve as a controllable mechanism to tune the phase configuration of transition metal dichalcogenide (TMD) bilayers.
Why it matters
Controlled phase engineering in 2D materials such as MoS2 is critical for the development of next-generation electronics, including low-power transistors, memory devices, and catalytic systems. The ability to trigger phase transitions through chemical doping rather than external stimuli offers a scalable and manufacturable pathway for device integration.
