摘要:

金刚石中的氮空位(NV)中心的集合体是实用量子传感器的领先平台。具有所需性能的NV系综的可重复和可扩展制造至关重要。这项工作通过开发化学气相沉积(CVD)合成工艺来解决这些挑战,以大规模生产具有针对目标NV密度的改善的NV系综性质的金刚石材料。在这项工作中报告的材料,使当前设备的灵敏度立即改善。此外,在这项工作中建立的技术,在CVD合成过程的不同阶段的材料和传感器表征提供指标,为未来的努力,针对其他NV密度或样品的几何形状。

英文摘要:

Ensembles of nitrogen-vacancy (NV) centers in diamond are a leading platform for practical quantum sensors. Reproducible and scalable fabrication of NV-ensembles with desired properties is crucial. This work addresses these challenges by developing a chemical vapor deposition (CVD) synthesis process to produce diamond material at scale with improved NV-ensemble properties for a target NV density. The material reported in this work enables immediate sensitivity improvements for current devices. In addition, techniques established in this work for material and sensor characterization at different stages of the CVD synthesis process provide metrics for future efforts targeting other NV densities or sample geometries.
