Δρ for neutral (a) and charged (b) CB defects in the system without external strain. The vertical dashed lines indicate the bond length value for the pristine structure. In the strain maps, red areas correspond to bond contraction, blue—bond elongation. The shorter C–N bonds labeled as “X” gave rise to overall increase in the length of the bonds next to the defect, as evident from asymmetric (with regard to the pristine system) bond length distribution.
