摘要:

我们证明了一个单一的氮空位(NV)在金刚石中心的三维本地化相结合的氮掺杂生长过程中与生长后12 C注入技术,促进空位形成的晶体。我们表明,NV密度可以控制注入剂量,而不需要增加氮掺入。通过纳米级孔径注入大剂量的12 C,我们可以将单个NV中心定位在(~180 nm)**3的体积内的确定性位置,同时可重复地保持相干时间(T2)> 300 μs。我们的方法能够将NV中心集成到金刚石纳米结构中,以实现可扩展的自旋传感器件以及由光子和声子介导的相干自旋耦合。

英文摘要:

We demonstrate three-dimensional localization of a single nitrogen-vacancy (NV) center in diamond by combining nitrogen doping during growth with a post-growth 12C implantation technique that facilitates vacancy formation in the crystal. We show that the NV density can be controlled by the implantation dose without necessitating increase of the nitrogen incorporation. By implanting a large 12C dose through nanoscale apertures, we can localize an individual NV center within a volume of (~180 nm)**3 at a deterministic position while reproducibly preserving a coherence time (T2) > 300 μs. Our approach enables integration of NV centers into diamond nanostructures to realize scalable spin-sensing devices as well as coherent spin coupling mediated by photons and phonons.
