Nitrogen-Vacancy Center (image) DOE/Lawrence Berkeley National Laboratory Caption Nitrogen-vacancy centers are defects in which a nitrogen atom substitutes for a carbon atom in the lattice and a vacancy left by a missing carbon atom is immediately adjacent, leaving unbonded electrons whose states can be precisely controlled. NV centers occur naturally in diamond or can be created artificially.
