- Abstract: Single photon emitters in solid-state crystals have received a lot of
attention as building blocks for numerous quantum technology applications.
Fluorescent defects in hexagonal boron nitride (hBN) stand out due to their
high luminosity and robust operation at room temperature. The identical emitter
fabrication at pre-defined sites is still challenging, which hampers the
integration of these defects in optical systems and electro-optical devices.
Here, we demonstrate the localized fabrication of hBN emitter arrays by
electron beam irradiation using a standard scanning electron microscope with
deep sub-micron lateral precision. The emitters are created with a high yield
and a reproducible spectrum peaking at 575 nm. Our measurements of optically
detected magnetic resonance have not revealed any addressable spin states.
Using density functional theory, we attribute the experimentally observed
emission lines to carbon-related defects, which are activated by the electron
beam. Our scalable approach provides a promising pathway for fabricating room
temperature single photon emitters in integrated quantum devices.
