Fig. 8: A summary of all the simulated cases on one negatively charged NV and one interstitial carbon.
From: Simulating the dynamics of NV− formation in diamond in the presence of carbon self-interstitials

a An illustration of PL signal in the experiment. b An illustration of 'Bright', 'Spike' and 'Dark' states together with their corresponding absorption spectrum. c Total energy variance for the simulated situations. d Spatial distribution for the classified situations. The NV− centre is located at the centre of the supercell, while the rest corresponds to interstitial carbon where 'Bright', 'Spike' and 'Dark' locations are marked in cyan, blue and black.
