NV/SiV Centers

Fluorescent color centers in diamond, especially the nitrogen-vacancy and silicon-vacancy centers, promise to enable several emerging applications in biological imaging, quantum sensing, and quantum computing. A major roadblock for many uses of color centers is the reliable and controlled synthesis of atomic defects within high quality diamond lattices. We aim to overcome these limitations by developing new fabrication methods to control the density, stability, and location of diamond fluorescent defects. Current work combines quantitative fluorescence methods with advanced nanofabrication techniques using both industrial substrates and custom synthesized diamond nanostructures.
