  • Many two-dimensional materials exhibit isotropic properties, but anisotropy can extend the functionality of future devices. Here, the authors fabricate field-effect transistors from single and few-layer rhenium disulfide and observe an anisotropic ratio of three to one along the two principle axes

  • The thinness and elastic properties of graphene make it an ideal candidate for nanoelectromechanical systems. Here, the authors demonstrate the positive piezoconductive effect in suspended bi- and multi-layer graphene, showing the most pronounced response for three layer samples.

  • A colour sensor array based on multilayer monolithically stacked lead halide perovskite thin-film photodetectors achieves higher quantum efficiency and superior colour accuracy compared to conventional filter-based image sensors.

  • An exciton polaron is a quasiparticle composed of an exciton dressed with an electron-hole cloud, and this concept has been used to explain the ground excitonic states in charged monolayer transition metal dichalcogenides. Here the authors present experimental and theoretical evidence of exciton-polaron Rydberg states in monolayer MoSe2 and WSe2.

  • Optical experiments on WSe2/MoSe2 heterobilayers reveal signatures of moiré trions, including interlayer emission with sharp lines and a complex charge-density dependence, features that differ markedly from those of conventional trions.
