AFM images of 5-nm-thick a-LAO (a) and c-LAO (b) films grown on STO substrate. The insets are surface profiles of the a-LAO/STO (rms roughness of 0.25 nm) and c-LAO/STO (rms roughness of 0.26 nm) heterostructures. The step heights of LAO/STO heterostructures (~0.4 nm) correspond to one unit-cell of LAO. c Cross-sectional high-angle annular dark field STEM images for an as-grown a-LAO/STO heterostructure
