Interlayer excitons (IXs) formed at the interface of
van der Waals
materials possess various novel properties. In parallel development,
strain engineering has emerged as an effective means for creating
2D quantum emitters. Exploring the intersection of these two exciting
areas, we use MoS2/WSe2 heterostructure as a
model system and demonstrate how strain, defects, and layering can
be utilized to create defect-bound IXs capable of bright, robust,
and tunable quantum light emission in the technologically important
near-infrared spectral range. Our work presents defect-bound IXs as
a promising platform for pushing the performance of 2D quantum emitters
beyond their current limitations.
