Monte Carlo simulations of (de)localized NC vacancies inside the SPs as a function of the attraction strength. (a) ε = 0 k_bT, the NC vacancy is delocalized over many lattice positions. (b) ε = −0.5 k_bT, long delocalized NC vacancies are not observed anymore, only weak delocalization of the NC vacancies over a maximum of a few lattice sites are observed. (c) ε = −1 k_bT, NC vacancies are exclusively observed on lattice positions and do not delocalize. The latter is also observed in the tomography experiments presented in Figure 4.
