Fig.8 Gaussian fitting results for the first shell of T(r) and the second shell g(r) (T(r)—radial distribution function, g(r)—pair distribution function) (a, b) fitting results of the first shell (a) and the second shell (b) of the sample Pd82Si18 that annealed for 200 s (1-atom—vertex-shared mode, 2-atom—edge-shared mode, 3-atom—face-shared mode, 4-atom—intercross-shared mode) (c) percentage of the Pd-Si and Pd-Pd atomic pairs obtained from the first shell fitting result of the sample Pd82Si18 annealed at 3 s, 200 s, and 2373 s (d) percent of 1-4 atomic connection obtained from the second shell fitting result of sample annealed at 3 s, 200 s, and 2373 s
