Asymmetric first peak in the g(r) of metallic liquids. a g(r) of constant-density Al liquids and corresponding inherent structures at various temperatures; b Schematic illustration of the asymmetry of the first g(r) peak, and the skewness increases upon heating; c Evaluation of r B/r A as the asymmetry of the first peak in g(r) at various temperatures for Cu, Al and Cu-Zr liquids (constant density). The definition of r B and r A are schematically shown at the full width of half maximum of the first peaks in the inset. d Average interatomic distance for atom pairs with shorter distance and longer distance in Cu melts at various temperature; (i.e., negative and positive departure from R IS, the first peak position in g(r) for the inherent structure).
