We report on electron paramagnetic resonance (EPR) studies of nitrogen doped diamond that has been (15)N enriched, electron irradiated and annealed. EPR spectra from two new nitrogen containing [Formula: see text] defects are detected and labelled WAR9 and WAR10. We show that the properties of these defects are consistent with them being the ⟨001⟩-nitrogen split interstitial and the ⟨001⟩-nitrogen split interstitial-⟨001⟩-carbon split interstitial pair, respectively. We also provide an explanation for why these defects have previously eluded discovery.
我们报告了对经过¹⁵N富集、电子辐照和退火处理的氮掺杂金刚石的电子顺磁共振（EPR）研究。检测到来自两种新的含氮[化学式：见正文]缺陷的EPR光谱，并将其标记为WAR9和WAR10。我们表明，这些缺陷的性质与它们分别是〈001〉-氮分裂间隙原子和〈001〉-氮分裂间隙原子-〈001〉-碳分裂间隙原子对一致。我们还解释了为什么这些缺陷此前一直未被发现。
