Fig. 6: ADF-STEM images of the pHPQ Zr50Cu40Al10 sample synthesized at 5.5 GPa and 880 K.

a ADF-STEM image of the sample. b High-magnification version of image in a. Left and right images are the ADF-STEM, and ABF-STEM images, respectively. Yellow dotted square shows typical Cu-rich ordered region. Yellow lines are traces of fringe-like contrast in the yellow dotted square. c Nanobeam electron diffraction patterns in the bright area in the ADF-STEM image. Area is different from that of a in the same pHPQ sample.
