Van der Waals crystals of transition metal dichalcogenide (TMD) semiconductors have evolved as an increasingly significant material platform for condensed matter research. They can be routinely exfoliated down to the monolayer limit or assembled into rationally designed vertical heterostructures. In response to optical excitations, both semiconductor systems host strongly bound excitons in various configurations of spin and valley degrees of freedom. [more]
