  • The authors investigate the interplay between the stacking order and the interlayer coupling in MoS2 homobilayers as well as artificially stacked bilayers grown by chemical vapour deposition, and identify the interlayer exciton absorption and A-B exciton separation as indicators for interlayer coupling.

  • Efficient second-harmonic generation (SHG) occurs for crystals with broken inversion symmetry, such as transition metal dichalcogenide monolayers. Here the authors show SHG tuning in bilayer MoS2 - an inversion-symmetric crystal - mediated by interlayer excitons.

  • Understanding light–matter interactions in layered materials is crucial for applications in photonics and optoelectronics. This Technical Review discusses the optical spectroscopy techniques to access details of the electronic band structure, crystal quality, crystal orientation and spin–valley polarization, including key aspects of practical set-ups to perform experiments for a broad range of applications.
