Van der Waals Heterostructures controlled by electromagnetic cavity resonators – CaVdW

Submission summary

2D materials and their van der Waals heterostructures have sparked a tremendous interest for their tunable electronic properties due to the electron spin, valley and layer degrees of freedom. New opportunities of control are emerging thanks to electromagnetic cavity resonators such as split-ring resonators with deeply sub-wavelength modal confinement and giant vacuum fields. Such resonators can modify not only the optical response, but also transport phenomena without illumination thanks to ultrastrong light-matter interaction. We will explore: (1) cavity-controlled charge transport in van der Waals heterostructures without illumination; (2) cavity-controlled electronic properties in presence of illumination; (3) novel Moiré superlattices, and their cavity control. This French-Hong Kong project would explore a cutting-edge research field and create synergy by enhancing complementary expertise of two experimental groups and two theoretical teams.
