Modulated interlayer exciton properties in a two-dimensional moiré crystal

Twisted van der Waals heterostructures and the corresponding superlattices, moiré superlattices, are remarkable material platforms, in which electron interactions and excited-state properties can be engineered. Particularly, the band offsets between adjacent layers can separate excited electrons and...
