论文摘要
我们报告了硅和氮共掺杂样品中钻石，SIV2-的双重缺陷的第一个实验性观察。我们测量钻石中替代硅的光谱特征，并鉴定出用理论计算支持的用最近的邻居氮SIVN装饰的硅胶合复合物。含有硅和氮的样品被证明是光色素的，由于SIV0/ - 的损失而具有显着的可见变化，并且在光学不活跃的SIV2-中获得了增益。
We report the first experimental observation of a doubly-charged defect in diamond, SiV2-, in silicon and nitrogen co-doped samples. We measure spectroscopic signatures we attribute to substitutional silicon in diamond, and identify a silicon-vacancy complex decorated with a nearest-neighbor nitrogen, SiVN, supported by theoretical calculations. Samples containing silicon and nitrogen are shown to be heavily photochromic, with the dominant visible changes due to the loss of SiV0/- and gain in the optically-inactive SiV2-.
