离子注入和退火形成的金刚石中氮空位中心的垂直分布

Vertical distribution of nitrogen-vacancy centers in diamond formed by ion implantation and annealing

摘要:

进行蚀刻实验,其揭示通过离子注入和退火在靠近表面处产生的金刚石中的光学活性氮空位(NV)中心的垂直分布。的NV分布强烈地依赖于原生氮浓度,和中性和带负电荷的NV峰的光谱测量提供证据,在较低的氮材料中的电子耗尽效应。这些结果对于潜在的量子信息和磁力计设备是重要的,其中NV中心必须被创建在非常接近于用于耦合到光学结构的表面处。

英文摘要:

Etching experiments were performed that reveal the vertical distribution of optically active nitrogen-vacancy (NV) centers in diamond created in close proximity to a surface through ion implantation and annealing. The NV distribution depends strongly on the native nitrogen concentration, and spectral measurements of the neutral and negatively-charged NV peaks give evidence for electron depletion effects in lower-nitrogen material. The results are important for potential quantum information and magnetometer devices where NV centers must be created in close proximity to a surface for coupling to optical structures.
