Fig. 1: Gold on amorphous carbon reconstruction results.
From: Sub-ångström resolution ptychography in a scanning electron microscope at 20 keV
a Exit wave produced by simulating the propagation of an electron plane wave through the multi-slice model produced by a ptychographic reconstruction on experimental 20 keV electron diffraction data obtained from gold particles supported on amorphous carbon, and (b) enlarged region of the reconstructed exit-wave. The colour scale for (a and b) is in the lower right corner of (b), where the colour wheel’s azimuthal angle, ϕ, represents the phase (spanning 0 – 2π) and the radial coordinate represents the amplitude of the wave, spanning an amplitude of 0.43 – 2.35. c Amplitude of the Fourier transform (FT) of the intensity of the reconstructed exit wave. In (c), the intensity is gamma adjusted by 0.9, the upper and lower 1% of pixels are saturated, and the colour scale, which linearly represents the amplitude0.9 is inset at the lower right. Scalebars: (a) – 10 nm, (b) – 5 nm, (c) – 1 Å−1.
