Composition-tunable transition metal dichalcogenide nanosheets via a scalable, solution-processable method.

ABSTRACT: The alloying of two-dimensional (2D) transition metal dichalcogenides (TMDs) is an established route to produce robust semiconductors with continuously tunable optoelectronic properties. However, typically reported methods for fabricating alloyed 2D TMD nanosheets are not suitable for the inexpensive, scalable production of large-area (m²) devices. Herein we describe a general method to afford large quantities of compositionally-tunable 2D TMD nanosheets using commercially available powders and liquid-phase exfoliation. Beginning with Mo_(1-x)W_xS₂ nanosheets, we demonstrate tunable optoelectronic properties as a function of composition. We extend this method to produce Mo_0.5W_0.5Se₂ MoSSe, WSSe, and qu
