  • Circular photocurrents emerge in atomically thin transition metal dichalcogenides as a result of circular photogalvanic and photon drag effects. Here, the authors identify two different circular photocurrent contributions in monolater MoSe2, dominant at different voltages and with different dependence on illumination wavelength and incidence angles.

  • As a material's thickness decreases towards the atomic-scale, dimensional confinement may promote behaviour not found in the bulk, with potential technological applications. Here, the authors study superconductivity in TaS2as it is mechanically exfoliated towards the two-dimensional limit.

  • A global network of researchers was formed to investigate the role of human genetics in SARS-CoV-2 infection and COVID-19 severity; this paper reports 13 genome-wide significant loci and potentially actionable mechanisms in response to infection.

  • Directional control of the diffusion of excitons is desired for excitonic devices, but being neutrally charged they can’t be transported by applying a bias voltage as for conventional electronic transport. It is now shown that surface acoustic waves can direct the flux of excitons over micrometre distances, even at room temperature.

  • The unique optical and optoelectronic properties of transition metal dichalcogenides are dominated by excitonic effects, whose structure is not fully characterised. Here, exciton and trion transitions in a monolayer MoS2 phototransistor are investigated by low temperature photocurrent spectroscopy.

  • Van der Waals epitaxy provides numerous opportunities for materials integration in heterostructures. This Primer provides an overview of methodologies for producing van der Waals heterostructures, focusing on top-down assembly and bottom-up synthesis, and discusses future opportunities for their continued development.
