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...

High-Speed Energy-Efficient Resonant Modulator on a Graphene-Organic Hybrid Platform

Abstract Resonant electro-optic modulators are of interest for encoding electrical signals to the optical domain with an option to perform simultaneous wavelength-division multiplexing while reducing the modulation energy consumption. Here, we demonstrate a compact, high-speed, a...
