The image is a compilation of the findings presented in the work. It includes the different dopant distribution lengths and Jahn‐Teller distortions observed in Ba‐, Sr‐ and Ca‐doped La 2 CuO 4 bilayer samples. Distribution lengths for each sample are marked with different colors located on an experimental STEM‐ABF image of the epitaxial layer. Moreover, contracted and expanded CuO 6 octahedrals depending on Jahn‐Teller and anti‐Jahn‐Teller distortions are illustrated with consistent color coding. More details can be found in article number 1700737 by Y. Eren Suyolcu and co‐workers.
