Fig. 3: Optical properties of defects in hBN polytypes.
From: Exceptionally strong coupling of defect emission in hexagonal boron nitride to stacking sequences

a Variations of transition dipole moments calculated for the three carbon defects in the different stacking sequences of hBN. b The simulated PL spectra of 6C defects in the \({{{\mbox{AA}}}}^{{\prime} }\) and \({{{\mbox{AB}}}}^{{\prime} }\) stacking sequences.
