Electronic properties and metrology applications of the diamond NV- center under pressure

Phys Rev Lett. 2014 Jan 31;112(4):047601. doi: 10.1103/PhysRevLett.112.047601. Epub 2014 Jan 31.


The negatively charged nitrogen-vacancy (NV-) center in diamond has realized new frontiers in quantum technology. Here, the optical and spin resonances of the NV- center are observed under hydrostatic pressures up to 60 GPa. Our results motivate powerful new techniques to measure pressure and image high-pressure magnetic and electric phenomena. Additionally, molecular orbital analysis and semiclassical calculations provide insight into the effects of compression on the electronic orbitals of the NV- center.
