Abstract Scope |
Nitrogen-vacancy (NV) centers in nanodiamonds are a promising single photon emitter (SPE) for applications such as secure quantum communication and magnetometry. However, their photo-emission properties can be impacted by factors such as diamond surface chemistry or distance between NV centers. An atomistic understanding of the NV center defect is therefore imperative for optimizing and utilizing its SPE properties. Here we use simultaneous electron energy loss spectroscopy (EELS) and energy dispersive X-ray spectroscopy (EDS) in a scanning transmission electron microscope (STEM) to unambiguously identify a single NV center in a particulate nanodiamond. We can further use the sub-angstrom probe of the STEM to reposition the N atoms in the diamond lattice, opening up a new pathway to pattern NV centers and study their interactions with one another. Identification and manipulation of these technologically relevant defects is an important first step toward single-atom quantum device fabrication. |
