Two-dimensional materials (2DM, e.g., graphene, boron nitride and transition metal dichalcogenides (TMDs)) compose a unique toolkit of one or a few atom-thick building blocks, whose characteristics can be combined and possibly enhanced by stacking them into van der Waals heterostructures. 2DM associate remarkable electronic, spin and valley properties with strong light-matter interactions, suitable for novel optoelectronic devices. In this seminar, I will present our investigations of charge vs energy transfer in atomically thin TMD-graphene heterostructures and discuss the relevance of these systems for room temperature opto-valleytronics.
