Modulated interlayer exciton properties in a two-dimensional moiré crystal
Modulated interlayer exciton properties in a two-dimensional moiré crystal
Twisted van der Waals heterostructures and the corresponding superlattices, moir\'e 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 holes, forming interlayer excitons that exhibit unique optical properties. In this work, we …
