  • Magneto-transport measurements on thin metallic crystals of the transition metal dichalcogenide PtSe2 show signatures of ferro- and antiferromagnetic order depending on the number of layers and first-principles calculations suggest Pt vacancies at the surface as a plausible cause.

  • Spatially and temporally resolved exciton diffusion experiments on a two-dimensional WSe2/hBN/MoSe2 heterostructure are reported, where an excitation-power-dependent exciton diffusion pattern is observed and phenomena with dipole–dipole repulsive interaction are quantitatively modelled.

  • Beneficiary defects could be utilized to introduce magnetism into materials that are not intrinsically magnetic. Here, the authors demonstrate long range magnetic order in the air-stable, defective Platinum Diselenide in the ultimate limit of thickness by using proximitized graphene as a probe.

  • The ability to control interlayer excitons in van der Waals heterostructures provides a practical way to address the spin and valley degrees of freedom in solid-state devices. This Review surveys the recent progress in this field, with a focus on devices and engineering techniques.
