TL;DR: It is demonstrated that high-crystalline mono- and few-layer WS2 flakes and even complete layers can be synthesized on sapphire with the domain size exceeding 50 × 50 μm(2) and it is interesting to see that, only through a mild sample oxidation process, the grain boundaries are easily recognizable by scanning electron microscopy due to its altered contrasts.

TL;DR: This study has successfully grown predominantly monolayer MoS2 on an inert and nearly lattice-matching mica substrate by using a low-pressure chemical vapor deposition method, and the homogeneously strained high-quality monolayers prepared in this study could competitively be exploited for a variety of future applications.

TL;DR: The observed oscillatory behavior of the superconducting transition temperature when the film thickness was increased by one atomic layer at a time suggests the possibility of modifying superconductivity and other physical properties of a thin film by exploiting well-controlled and thickness-dependent quantum size effects.

TL;DR: The scalable growth of high quality, domain size tunable, strictly monolayer MoS2 flakes or even complete films on commercially available Au foils, via low pressure chemical vapor deposition method is reported, and it is presented sound proof that monolays2 assembled on a well selected electrode can manifest a hydrogen evolution reaction property comparable with that of nanoparticles or few-layer MoS 2 electrocatalysts.

TL;DR: By applying controlled current pulses, the upper Pc ligand in TbPc2 is rotated, leading to the disappearance and reappearance of the Kondo resonance, and reversible switching between two stable ligand orientations by applying a current pulse is made possible.
