Figure 8
(top) Simulated HAADF STEM images from the model with space groups P6₃mc (#186) and P6₃/mmc (#194) using Dr. Probe software and a frozen lattice procedure (50 frozen states and total thickness of 20 nm) compared to the experimental one. (bottom) Compilation of the horizontal line profiles of the HAADF intensities integrated over the height of the image. The vertical arrows in the intensity profiles and in the HAADF images point to the same double-Al atomic plane. For an easier comparison, intensity curves were background corrected and normalized at the Al(C,N) atomic plane (close to 0.4 nm).
