TL;DR: It is found that weak Ar-plasma bombardment can locally induce 2H→1T phase transition in monolayer MoS2 to form mosaic structures, which open up a new route for phase engineering in MonolayerMoS2 and other transition metal dichalcogenide (TMD) materials.

TL;DR: It is reported that domain boundaries in the basal plane of monolayer MoS2 can greatly enhance its hydrogen evolution reaction performance by serving as active sites, and it is demonstrated that such superior catalysts are feasible at a large scale by applying this multi-hierarchy design of domain boundaries to wafer-scale MonS2 films.

TL;DR: In this article, the authors used a modified chemical vapour deposition process to grow wafer-scale monolayers with large grain sizes and gold/titanium/gold electrodes to create a contact resistance as low as 2.9

TL;DR: In this article, the state-of-the-art physical and chemical approaches to symmetry breaking of 2D layered materials and their heterostructures are discussed, and the perspectives on how these may lead to new physics and applications are discussed.
