TL;DR: This work presents a self-limiting approach that can grow high quality monolayer and few-layer MoS2 films over an area of centimeters with unprecedented uniformity and controllability and paves the way for the development of practical devices with 2DMoS2 and opens up new avenues for fundamental research.

TL;DR: A surface-energy-assisted process that can perfectly transfer centimeter-scale monolayer and few-layer MoS2 films from original growth substrates onto arbitrary substrates with no observable wrinkles, cracks, and polymer residues is demonstrated.

TL;DR: In this article, the authors demonstrate that 2D MoS2/WS2 heterostructures can enable equally efficient interlayer exciton relaxation regardless the epitaxy and orientation of the stacking.

TL;DR: This result indicates that 2D heterostructures bear significant implications for the development of photonic devices, in particular those requesting efficient exciton separation and strong light absorption, such as solar cells, photodetectors, modulators, and photocatalysts, and suggests that the simple stacking of dissimilar 2D materials with random orientations is a viable strategy to fabricate complex functional 2Dheterostructure.

TL;DR: In this paper, it was shown that the luminescence efficiency of monolayers composed of MoS2, WS2, and WSe2 is significantly limited by the substrate and can be improved by orders of magnitude through substrate engineering.
