Fig. 3: Atom distributions and 1D local density profiles near voids based on field-evaporation simulations.

Fig. 3

a and d show results with Eshell = 0.7 Ematrix; b and e show results with Eshell = Ematrix; c and f show results with Eshell = 1.3 Ematrix. Atom distributions in a, b, c are from 11.2 × 8.3 × 1 nm cuboidal ROIs near the void projected onto the x direction in the simulated APT reconstructions. Each dot represents one atom, with Co, Ni, and Cr atoms shown as blue, green, and red dots, respectively. 1D profiles are calculated using a 11 nm long × 3 nm diameter cylindrical ROI through the void center and are oriented parallel to the evaporation direction of the simulated APT reconstruction.
