Abstract

Owing to an error in properly normalizing the reconstruction phase data into atomic displacements, the strain values that we used to calculate the root mean squared local strain, ɛrms, and to calculate the fraction of the crystals more strain than 1%, f, quoted in the original paper, are roughly one order of magnitude too large. This error was only discovered recently whilst performing further analysis. The crystals still contain regions that are highly strained. We emphasize that this correction is for the sake of accuracy in the academic record, and our errors do not change any of the conclusions drawn in this work. We apologize to the readership for this error. Additionally, in the discussion we erroneously stated that the halide sublattice of halide perovskites was face-centred cubic (FCC) when it is, in fact, the halide + A-site sublattice that is FCC. We highlight below the specific short excerpts of text and figures that need correcting. The page and paragraph numbers refer to the online PDF of the paper at https://onlinelibrary.wiley.com/doi/epdf/10.1002/adma.202305549. Corrections to the main text: Main text: Figure 1e: The histogram in panel e should be replaced with a corrected histogram. The corrected figure is below. Original figure: Main text: caption of Figure 1: Penultimate sentence: “Local strain values exceeding a magnitude of 1% are highlighted in orange.” should be omitted as, on the new scale for the histogram presented in Figure 1e, these regions are not visible. Final sentence: “The root mean squared local strain, ɛrms, and fraction of the crystal volume with local strain exceeding 1%, f, are quoted.” Should be replaced with “The root mean squared local strain, ɛrms, is quoted.” f is no longer quoted, as it is negligible for this crystal. Main text: page 3, paragraph 2: In the sentence starting “Figure 1e shows…”, the clause “, with those of magnitude greater than 1% highlighted in orange” should be omitted. In the sentence starting “For this crystal, …”, the clause “f, is 13.2%, and the root mean squared value of local strain, ɛrms, is 0.7%.” should read “f, is negligible and the root mean squared value of local strain, ɛrms, is 0.066%.” In the sentence starting “These values are…”, the clause “we find 5% < f < 30% and 0.5% < ɛrms < 4.5%” should read “we find 0% < f < 3.5% and 0.05% < ɛrms < 0.45%”. Main text: page 5 final paragraph: In the sentence starting “While we cannot…”, the clause “both f (13.2% to 48.0%) and ɛrms (1.0% to 5.1%)” should read “both f (0.12% to 2.42%) and ɛrms (0.092% to 0.481%)”. Main text: Figure 4: The ɛrms, and f labels should be replaced with their corrected values. The corrected figure is below. Original figure: Main text: page 6 paragraph 3: In the sentence starting “The face-centered cubic…”, the clause “and the halide sublattice” should read “and the halide + A-site sublattice”. In the sentence starting: “Given that the dislocations…”, the clause “it is likely that the ions of the FCC halide sublattice” should read “it is likely that the halide ions of the FCC halide + A-site sublattice”. Corrections to the Supporting Information: Table S1 (Supporting Information): This table should be replaced with the following, where we have corrected the values of f and ɛrms. (Table presented.) Caption to Table S1 (Supporting Information): “(shown by the orange regions of the histogram in Figure 1e of the main text)” should be omitted as, on the new scale for the histograms, these regions are not visible. Figure S23 (Supporting Information): The ɛrms, and f labels should be replaced with their corrected values. The corrected figure is below. Original figure: Figure S27 (Supporting Information): Histograms with corrected axes are presented below. Original figure: Figure S28 (Supporting Information): Histograms with corrected axes are presented below. Original figure: Figure S29 (Supporting Information): Histograms with corrected axes are presented below. Original figure: Captions of Figures S27–S29 (Supporting Information): “Values with a magnitude greater than 1% are highlighted in orange.” should be omitted as, on the new scale for the histograms, these regions are not visible.
