The calculated stacking fault structures with vacuum layers. (a) The SISF model with a B-type layer was removed, (b) the SISF2 model with the ABAB layer inserted in it, (c) the SESF model with an A-type layer inserted in it. The green balls represent the Ni atoms, and the pink balls represent the Al atoms in the models. The layers in the grey plane were fixed during the calculations and the layers with the blue were the location of the stacking faults.
