TL;DR: In this paper, single-crystal islands and polycrystals containing tilt and mirror twin grain boundaries are characterized, and the influence of the grain boundaries on the material properties of molybdenum disulphide is assessed.

TL;DR: It is shown that cyclic stretching and releasing of thin MoS2 flakes with an odd number of atomic layers produces oscillating piezoelectric voltage and current outputs, whereas no output is observed for flakes with even number of layers, which may enable the development of applications in powering nanodevices, adaptive bioprobes and tunable/stretchable electronics/optoelectronics.

TL;DR: In this article, the microstructure of monolayer molybdenum disulfide has been studied and the authors show that triangular islands are single crystals and merge to form faceted tilt and mirror boundaries that are stitched together by lines of 8- and 4- membered rings.

TL;DR: Modelling of potential scattering sources and quantum lifetime analysis indicate that a combination of short-range and long-range interfacial scattering limits the low-temperature mobility of MoS2.

TL;DR: In this paper, the complex in-plane dielectric function from 1.5 to 3 eV for monolayers of four transition metal dichalcogenides (MoSe 2, WSe2, MoS2, and WS2) was presented.
