Research paperExperimental CharacterizationCathodoluminescence monitoring of quantum emitter activation in hexagonal boron nitrideSébastien Roux, Clarisse Fournier, Kenji Watanabe, Takashi Taniguchi et al.arXiv preprint·2022·10.1063/5.0126357·arXiv:2210.05028AbstractCathodoluminescence (CL) is used to monitor in situ the local activation of color centers in hexagonal boron nitride (hBN) by an electron beam. The CL signal saturates at a given surface dose independently of electron current density. Photoluminescence (PL) and photon-correlation measurements are used to estimate the number of photoactive quantum emitters generated and to infer the activation efficiency and maximum emitter density.Read more
