Abstract:
Solid-state quantum sensors are attracting wide interest because of their sensitivity at room temperature. The spin properties of individual nitrogen vacancy NV color centers in diamond make them outstanding nanoscale sensors of magnetic fields, electric fields, and temperature under ambient conditions. Using large ensembles of NV centers leads to increases in sensitivity with reduced spatial resolution. A power efficient device for the implementation of diamond-based sensors using large ensembles 1010 of NV centers with sub-millimeter-scale spatial resolution is described and demonstrated. The challenges of working with large ensembles of defects are be discussed, as well as several strategies for combatting sensitivity-limiting ambient temperature fluctuations. Magnetometry, temperature sensing, and time keeping applications are explored.
