Extended Data Fig. 4: Angular errors in the experimental images and verification of the experimental 3D atomic model using multi-slice simulations.
From: Determining the three-dimensional atomic structure of an amorphous solid
a, Angular errors in the experimental images determined by an angular refinement procedure (Methods), where the colour dots and lines represent the deviation of the three Euler angles (ϕ, θ and φ) from the correct ones (0°) at each tilt angle. These angular errors were taken into account in the multi-slice simulations. b, The angular errors were correctly refined in the 3D reconstruction of the 55 multi-slice images using RESIRE (Methods). After the angular refinement, the largest error is only 0.2°. c, d, Comparison between a representative experimental (after denoising) (c) and a multi-slice (d) image at 0°. To account for the source size and incoherence effects, each multi-slice image was convolved with a Gaussian function (Methods). e, Histogram of the deviation of the atomic positions between the experimental atomic model and that obtained from 55 multi-slice images. The peak, mean and root-mean-square deviation of the histogram are 6 nm, 15 nm and 21 pm, respectively. Scale bar, 2 nm.
