Investigation of near-surface defects of nanodiamonds by high-frequency EPR and DFT calculation
Investigation of near-surface defects of nanodiamonds by high-frequency EPR and DFT calculation
Nanodiamonds (NDs) hosting nitrogen-vacancy (NV) centers are a promising platform for quantum sensing applications. Sensitivity of the applications using NV centers in NDs is often limited due to the presence of paramagnetic impurity contents near the ND surface. Here, we investigate near-surface paramagnetic impurities in NDs. Using high-frequency (HF) electron …
