摘要:

我们提出了一种很有前途的方法,用于创建高密度合奏的氮空位中心与窄自旋共振高灵敏度磁成像。实际上,窄的自旋共振线宽大大降低了基于系综的感测的光学和RF功率要求。该方法结合同位素纯化金刚石生长,原位氮掺杂,和氦离子注入,以实现100 nm厚的传感表面。得到的10^(17)cm^(-3)氮空位密度仅比迄今为止报道的最高密度小10倍,观察到的自旋共振线宽窄10倍以上。200 kHz线宽最有可能受到偶极展宽的限制,这表明线宽的进一步减小是期望的和可能的。

英文摘要:

We present a promising method for creating high-density ensembles of nitrogen-vacancy centers with narrow spin-resonances for high-sensitivity magnetic imaging. Practically, narrow spin-resonance linewidths substantially reduce the optical and RF power requirements for ensemble-based sensing. The method combines isotope purified diamond growth, in situ nitrogen doping, and helium ion implantation to realize a 100 nm-thick sensing surface. The obtained 10^(17) cm^(-3) nitrogen-vacancy density is only a factor of 10 less than the highest densities reported to date, with an observed spin resonance linewidth over 10 times more narrow. The 200 kHz linewidth is most likely limited by dipolar broadening indicating even further reduction of the linewidth is desirable and possible.
