Fig. 5: High-magnification BF-STEM images of the pHPQ Zr50Cu40Al10 sample synthesized at 5.5 GPa and 880 K.

a BF-STEM image of the sample. b High-magnification version of image in a. Atomic distances in the nano-ordered region are estimated to be the first (orange), second (light blue), and third (light green) neighbor distances of ~3.0 Å, ~5.0 Å, and ~7.6 Å, respectively. c Comparison between the atomic neighbor distances in b and g(r). Black and green curves denote g(r) of the as-cast sample, and the pHPQ sample treated at 5.5 GPa and 870 K, respectively. Orange, light blue, and light green vertical bars denote the multiple values of the first, second, and third-neighbor distances, respectively.
