Fig. 4From: Atomap: a new software tool for the automated analysis of atomic resolution images using two-dimensional Gaussian fittingComparison of geometrical phase analysis (GPA) and the method outlined in this work for determining the out-of-plane lattice parameter. a STEM-HAADF image of an LSMO film grown on STO-(111). Top inset is an FFT of the LSMO region, showing a clear superstructure compared to the STO substrate FFT in the lower inset. b Average interplanar distance for the A-cation (111) atom planes as a function of distance from the LSMO/STO interface. The blue solid line shows the result from the method outlined in this paper, and the dashed green line from GPABack to article page
