Abstract: A small sample tilt away from a main zone axis orientation results in an elongation of the atomic columns in ADF STEM images. An often posed research question is therefore whether the ADF STEM image… read more here.

DOI: 10.1017/s1431927618000788
Abstract: Picometer-scale structural distortion drives a wide range of material properties including pyroelectricity, ferroelectricity, and piezoelectricity. Further, since short-range correlations of chemistry and distortion in these systems manifest unique properties, it is crucial to quantify and… read more here.
