Isolating 2D materials from non-van der Waals (non-vdW) layered structures by mechanical cleavage is challenging owing to strong electronic coupling between adjacent layers. We show that mechanically sliding the layers weakens interlayer interactions, enabling delamination of a wide range of non-vdW layered structures to produce 2D sheets with unusual thickness-dependent physical properties.

Mechanical cleavage of layered materials to obtain two-dimensional (2D) sheets is restricted to materials with interlayer interactions dominated by van der Waals (vdW) forces. Here, calendering is used to weaken interlayer binding in non-vdW layered structures (metals, semiconductors and superconductors) allowing mechanical exfoliation to obtain 2D sheets with thickness-dependent properties.

The authors report a crossover from easy-plane to easy-axis magnetic anisotropy in monolayer RuCl3, which they attribute to an in-plane distortion of the Cl atoms observed in electron diffraction that modify the non-Kitaev exchange terms. The results are useful for overcoming the challenge of realizing a quantum spin liquid.

Low-power and compact active pixel sensor (APS) matrices are desired for resource-limited edge devices. Here, the authors report a small-footprint APS matrix based on monolayer MoS2 phototransistors arrays exhibiting spectral uniformity, reconfigurable photoresponsivity and de-noising capabilities at low energy consumption.

A strong and tough human muscle-like actuator fibre is developed by exploiting 2D graphene fillers within a liquid crystalline elastomer matrix. Reversible percolation of the graphene filler network endows the artificial muscle with a work capacity and power density beyond those of human or mammalian muscles.
