nLab nitrogen-vacancy center in diamond

Contents

Idea

In solid state physics, an impure form of diamond may be obtained where, in the center of the Bravais lattice, carbon nuclei are replaced by a nitrogen nucleus and a vacancy, referred to as the nitrogen-vacancy center in diamond (often short: NV center).

In such a material, the spin of one of the electron orbitals bound to the nitrogen nucleus has a long quantum decoherence time and lends itself to manipulation by spin resonance.
