Strain maps for (a) anion and (b) cation sublattices. (c) and (d) Strain profiles averaged over 52 unit cells for the anion and cation lattices, respectively, showing the compressive strained GaSb and tensile strained InAs. (e) and (f) Standard deviations of the measured strain in each monolayer, drawn as blue circles. The solid black lines in panels (e) and (f) indicate the averaged standard deviation of the strain in each layer of the InAs/GaSb SLS. The red circles in panels (c) and (d) and the white open circles in panels (a) and (b) indicate where large strain deviations from the mean are observed. The AlSb barrier is not shown in panel (b) because the intensity of the Al (Z = 13) columns is too weak to locate its position.
