Calculated images of a small gold crystal (3 by 3 by 3 unit cells near the center) on a thin amorphous carbon support (20 Å thick) at 200 kV and CS3 = 0.7 mm. (a) BF-CTEM, = 520 Å, objective aperture 12 mrad, (b) ABF-STEM, = 520 Å, objective aperture 12 mrad, (c) ABF-STEM, = 365 Å, objective aperture 10.5 mrad, (d) ADF-STEM, = 365 Å, objective aperture 10.5 mrad. Scale bar is 10 Å. |
