The Re atoms and their NN Ni atoms in the models with single Re atoms near the interface. (a) the system with Re atom at Al site in γ′ side near the interface, which corresponds to system S5 in Fig. 2; (b) the system with Re atom at Ni site in γ′ side near the interface, which corresponds to system S5′ in Fig. 2; (c) the system with Re atom in γ side near the interface, which corresponds to system S6 in Fig. 2.
