D’AlessandroarXiv·2026·arXiv:2605.24027AbstractFirst-principles and many-body perturbation theory calculations are used to study hydrogenated graphene superlattices (AGSLs). The work shows that selective hydrogenation opens direct band gaps and produces strong excitonic absorption peaks that can be tuned into the far-infrared and toward the terahertz range by increasing the separation between hydrogen lines.Read more
