Towards terahertz excitons in hydrogenated graphene superlattices

This study uses first-principles calculations to demonstrate that selectively hydrogenating graphene to create alternating quasi-metallic and dielectric superlattices enables the formation of strong, well-isolated excitonic absorption peaks in the terahertz and far-infrared ranges, offering a viable route for on-chip terahertz components without the integration challenges faced by carbon nanotubes and nanoribbons.
