Measurement of quantum efficiency of B-centre in thin hexagonal boron nitride
B-centres in hexagonal boron nitride, activated by electron beam irradiation, offer precise, reproducible single-photon emission critical for quantum photonics. We measure quantum efficiency, surpassing 40%, and explore conditions for near-unity QE, advancing quantum technologies.
