Figure 4
Image simulation for different types of point defect. The top row shows structure models for (a) vacancy, (b) antisite and (c) substitutional defects, as marked by red arrows. The middle row displays simulated Z-contrast images, where the atomic distances are compared with the original structure without defects. The bottom row shows difference images between structures with and without defects. The numbers in the middle row indicate the changes in bond lengths due to point defects.
