Fig. 2

a Medium-range order (MRO) structure composed of Hf docosahedral (@4(56)258) atomic clusters. The circular dashed line indicates the beam size. a’, Simulated angstrom-beam electron diffraction (ABED) pattern of the model shown in (a). b MRO structure identical to (a), except oxygen atoms are removed. b’ Simulated ABED pattern of the model shown in (b). c Spatially-averaged experimental ABED pattern obtained from an amorphous HfO2 film. d Experimental ABED pattern obtained from a local region of an amorphous HfO2 film.
