Here, we demonstrate the targeted, high throughput formation of NV centers using masks with a thickness of 270 nm and feature sizes down to ~1 nm. Super-resolution imaging resolves NVs with a full-width maximum distribution of $26\\pm7$ nm and a distribution of NV-NV separations of $16\\pm5$ nm.","authors_text":"Aaron Stein, Dirk Englund, Edward H.
