| Abstract Scope |
Single-photon-emitting color centers in nanodiamonds are an appealing architecture for quantum systems. In addition to strong single-photon photoluminescence from the color centers, diamond has many advantages, such as chemical inertness, mechanical hardness, and zero nuclear spin. Nitrogen-vacancy (NV) centers in nanodiamonds are among the most promising potential single-atom quantum systems. However, unambiguously locating a single NV center in a nanodiamond is challenging. Here, we perform simultaneous electron energy loss spectroscopy (EELS) and energy dispersive x-ray spectroscopy (EDS) spectrum imaging in an aberration-corrected scanning transmission electron microscope (STEM) to identify the NV centers, using the characteristic 282.4 eV peak in the C K-edge fine structure EELS data and the nitrogen signal at 0.39 keV in the EDS data. This atomic-scale identification of NV centers in the STEM is a potential first step towards in situ single-atom quantum device fabrication using the electron beam to control color center positioning. |
