  • Excitonic states govern the optical response of low-dimensional nanomaterials and are key for a wide range of applications. Here, the authors investigate the exciton decay dynamics in single carbon nanotubes with few-exciton detection sensitivity.

  • Ultrathin multilayer van der Waals material stacks are shaped into precisely engineered resonant nanostructures, giving strong nonlinearities at ultralow fluences of <1 nJ cm–2, more than three orders of magnitude smaller than in previous two-dimensional-material-based cavity systems.

  • Defects can significantly alter the physical properties of materials. A detailed experimental analysis of defects in carbon nanotubes enables the relationship between the atomic response and the broadly available macrosopic behaviour to be captured.
