Atomically resolved exciton emission from single defects in MoS2

Abstract Excitons, bound electron–hole pairs, govern the optical response of semiconductors and underpin technologies ranging from photovoltaics to quantum light sources. In nanoscale systems, the spatial extent of excitons approaches atomic dimensions, yet direct imaging of exci...

Electrically reconfigurable dipolar polaritons with highly tunable nonlinearity in a homobilayer microcavity

Active control over optical nonlinearity in solid-state systems is central to unlocking exotic many-body phenomena and photonic devices. While exciton-polaritons in transition metal dichalcogenides (TMDs) offer a promising platform, their practical utility is impeded by fixed int...
