Symposium EQ03-Spin-Based Sensing at the Nanoscale and Hyperpolarization with NV-Diamond and Beyond

Point defects like nitrogen vacancy centers (NV) in diamond can serve as highly sensitive and atomically small sensors making them ideal for localized measurements on the nanoscale. The spin state of a single NV center can be controlled and read-out optically enabling the detection of magnetic fields. Spin-based analytical methods like nuclear magnetic resonance spectroscopy are non-destructive and obtain information on a molecular level. They are routinely used for structure determination and quality control. The measurement principle is based on the interaction of individual nuclear spins under a strong magnetic field causing spin alignment. NV centers in close proximity to the analyte drastically decrease the sample volume simultaneously increasing spatial resolution. In addition, by hyperpolarization, spin polarization can be transferred e.g., from NV centers to other nuclei, beyond the thermal equilibrium, increasing the measurement signal. The material plays a key role for these techniques as material quality (defect density, contaminations, etc.) strongly influence decoherence times effectively reducing measurement time and hence increasing uncertainty. Apart from diamond, other materials like SiC and BN can host usable vacancy defects and are gaining more and more attention. Defects close to the surface show higher sensitivity to the adjacent magnetic field, however, in liquids fermi level shifts can result in discharging, i.e., sensor deactivation.

In this symposium, we want to address the challenges in spin-based sensing and hyperpolarization from the material synthesis to the application with a strong focus on diamond materials. This includes advanced defect and material characterization, diamond technology, surface treatments, spin manipulation protocols, biological applications and many more. Joint sessions on general diamond growth and doping will be organized to strenghten scientific exchange.

  • Synthesis of NV-doped and Ultrapure Diamond
  • Other NV-like systems and materials
  • Creation of Color Centers
