Creating nitrogen-vacancy centers (NVs) in isotopically controlled diamond layers by CVD diamond growth — •Christian Osterkamp, Takashi Yamamoto, Boris Naydenov, and Fedor Jelezko — Universität Ulm, Institut für Quantenoptik

The negatively charged nitrogen-vacancy center (NV) is amongst the leading solid-state quantum bits. The fluorescence of single NVs can be detected and its electron spin can be polarized, read-out and manipulated at ambient conditions. Creation of NVs on demand is an important task for quantum technology applications like quantum computers or magnetic- and electric field sensors [1]. We engineer NVs by delta doping during a plasma enhanced chemical vapor deposition (PECVD) process [2] and we are able to produce isotopically pure diamonds by changing the ratio of 12C/13C atoms in the growth chamber.
