Indirect Overgrowth as a Synthesis Route for Superior Diamond Nano Sensors

C. Findler, J. Lang, et al.

This exciting research by Christoph Findler, Johannes Lang, Christian Osterkamp, Miloš Nesládek, and Fedor Jelezko unveils a novel method called indirect overgrowth, significantly enhancing diamond nano sensors with nitrogen-vacancy centers. By reducing the passivation to NVH centers, their findings promise improved coherence times and are set to revolutionize quantum sensing applications!

Abstract

This paper investigates the use of indirect overgrowth, a method combining low-energy nitrogen ion implantation and chemical vapor deposition (CVD) diamond growth, to improve the properties of diamond nano sensors based on nitrogen-vacancy (NV⁻) centers. The authors find that indirect overgrowth significantly reduces the passivation of NV⁻ centers to NVH centers during the growth process, leading to enhanced coherence times (T₂ and T₂*) and a high degree of depth confinement. This improved understanding of CVD diamond overgrowth paves the way for more reliable and advanced engineering of shallow NV⁻ centers for quantum sensing applications.
