Capillary assembly of large arrays of hBN single-photon emitters

The availability of efficient and robust quantum light sources in large numbers is one of the key building blocks for quantum photonic technology. Recently, bright and stable single-photon emitters have been discovered in the 2D material hexagonal boron nitride (hBN), which efficiently emit single photons even at room-temperature [1] . The controlled positioning of nanocrystals hosting light emitters is an important technique for the bottom-up fabrication of functional nanostructures as well as for fundamental investigations on the particles themselves.
