Title Excitons in van der Waals heterostructures
Abstract Van der Waals crystals of two-dimensional semiconductors have evolved as an increasingly significant material platform for condensed matter research. Using exfoliated monolayers, a wide range of vertical van der Waals heterostructures can be assembled into rationally designed material systems with tailored optical properties of strongly bound excitons. In my talk, I will discuss the results of our recent studies of various van der Waals heterostructure assemblies and highlight the roles of layer constituents, number, twist angle and atomic registry.
