Figure 1435 shows HAADF-STEM and SE images of a gold nanoparticle, indicating that Au (111) lattice fringes with a 0.24 nm lattice spacing are visible in both images. However, the signal-to-noise ratio of the HAADF-STEM image is much greater than that of the SEM image. The two images were recorded simultaneously on a Cs-corrected HD-2700 STEM/SEM. The accelerating voltage and the probe size were 200 kV and 0.1 nm, respectively.
