“…We note that these findings agree with previous reports in which low-angle unfiltered STEM served for qualitative analyses in thick specimen474849 whereas quantitative agreement was found in bright field STEM in thin specimens where the fraction of inelastic intensity is low50. Moreover, energy filtered diffraction patterns at elevated thicknesses agreed with simulations, too515253.…”

“…4D STEM data are recorded at atomic resolution without energy filtering, in addition with a 10 eV wide energy window centered around zero loss, and a 30 eV wide energy window centered around the first plasmon peak at ∼ 22.6 eV. The thickness is again evaluated using the comparison between the zero-loss filtered diffraction patterns and an elastic PACBED simulation 40 . Figure 3d depicts the differential intensities derived at the thinner, i.e.…”

“…Interestingly, all experimental measurements are clustered along a single trend line and our measurement is fairly close to another measurement made by electron diffraction. [23] Fig. 6f shows the difference between best-fit simulation and experiment at room temperature.…”

“…Even worse, electrons scattered in this way may be subsequently Bragg diffracted, producing a strongly structured background that is difficult to subtract. For this reason, energy filtering is often seen as essential for accurate results, [8,23] which adds yet another experimental complication and barrier to use.…”
