Figure 5: On the enhanced accuracy of electric field measurement near heavy atomic columns at lower specimen thickness.
From: Atomic electric fields revealed by a quantum mechanical approach to electron picodiffraction
Electric field determined from simulated ronchigrams of SrTiO3 at 1.6 nm specimen thickness. This shows that remaining inaccuracies of the measured field in Fig. 3c in the explicit vicinity of atomic columns with heavy atoms are due to specimen thickness. To be compared directly with the theoretical result in Fig. 4a. Length of the black legend vector is 1 V pm−1, scale bar is 100 pm.
