    2020-6-24 · We characterize single nitrogen-vacancy (NV) centers created by 10-keV N + ion implantation into diamond via thin SiO 2 layers working as screening masks. Despite the relatively high acceleration energy compared with standard ones (< 5 keV) used to create near-surface NV centers, the screening masks modify the distribution of N + ions to be peaked at the diamond surface [Ito et al., …

    2006-10-17 · The poorest service I've gotten is from Eze-lap products which seem to lose aggression fairly fast. The inexpensive diamond hones from Harbor Freight have actually served me better. The monocrystalline DMT hones retain aggression much longer. I've also used a large Norton plate that's had plenty of use before and it seems to be an excellent ...

    2020-5-20 · In addition, since homoepitaxial layers on (110)-oriented diamond substrates have one of the highest growth rates under standard CVD conditions , the top surface tends to rapidly disappear during growth, limiting the final surface area when thick films are required.
