TL;DR: This work demonstrates the chemical vapor deposition (CVD) growth of uniform MoSe2 monolayers under ambient pressure, resulting in large single crystalline islands, and shows n-type channel behavior with average mobility much higher than the 4-20 cm(2) V(-1) s-1 reported for vapor phase grown MoS2.

TL;DR: This work demonstrates for the first time a two-step chemical vapor deposition (CVD) method for growing transition-metal dichalcogenide (TMD) heterostructures, where MoSe 2 was synthesized first and followed by an epitaxial growth of WSe2 on the edge and on the top surface of MoSe2.

TL;DR: This study provides distinctive insight into LPE and has pioneered a rational strategy for LPE of 2D materials with high yield.

TL;DR: The electrocatalytic hydrogen evolution reaction (HER) activities of VS2 show an extremely low overpotential, small Tafel slopes, as well as high stability, demonstrating its potential as a candidate non-noble-metal catalyst for the HER.

TL;DR: In this article, the electronic factors underlying catalytic activity on MX-2 surfaces were unraveled and leverage the understanding to report group-5 MX2 electrocatalysts whose performance instead mainly derives from highly active basalplane sites, as suggested by first-principles calculations and performance comparisons with edge-active counterparts.
