  • Grain boundaries can degrade the performance of electronic devices made from single atomic layers of transition metal dichalcogenides. Here, the authors combine transport measurements and transmission electron microscopy to find a correlation between field-effect mobility and grain misorientation angle.

  • Wafer-scale growth of rhombohedral-stacked molybdenum disulfide is achieved through homoepitaxy promoted by intrinsic defects, which enables scalable and fatigue-resistant ferroelectric field-effect transistors.

  • How well the linear elastic fracture picture holds at small length scales and systems with reduced dimensionality remains an active area of inquiry. Here authors usein situ electron microscopy to study fracture in MoS2monolayers and report dislocation emission rates greater than expected accompanying crack propagation.

  • Despite recent progress in the production of bendable thin-film transistors, their development is limited by leakage currents and fragile inorganic oxides. Combining graphene and single-walled carbon nanotube electrodes with a geometrically wrinkled inorganic layer, highly stretchable and transparent field-effect transistors have now been demonstrated.

  • The metal monochalcogenides are a group of van der Waals layered semiconductors with ultra-high plasticity. It is now revealed that their plasticity is attributed to the ability to transform their stacking order or phases, coupled with the concurrent generation of a micro-crack network.

  • Surface amorphization generally provides electrocatalysts with more active sites and flexibility. Here it is employed in-situ liquid TEM to observe the surface reconstruction on Ru-NiPS3 nanosheets, confirming that the amorphization on the edges of NiPS3 is critical for achieving superior activity.

  • Here, the authors use in situ transmission electron microscopy to measure the interface properties of electrical contacts with MoS2, ReS2, and graphene, and find that direct quantum tunnelling across van-der-Waals-bonded interfaces is more favourable than Fowler–Nordheim tunnelling across chemically bonded interfaces.

  • The extraordinary mechanical properties of graphene are usually measured on very small or supported samples. Here, the authors develop a method to test a large area of graphene and show that even with edge defects it displays near-ideal mechanical performance.

  • Two-dimensional materials have well-defined atomic-scale structure, which has the potential to be tuned by processing. Here, substrate-induced straining during the growth of ReS2 causes the formation of martensite-like domain structures.
