(color online) 2D and 3D analysis of strain distribution of an Au nanodecahedron. The strain distribution is visualized using a color code and scaled between ± 5%. (a) The ε_xx strain map obtained from a STEM-HAADF projection image. (b) The corresponding lattice displacement along the x-direction. (c) Slice through the ε_xx volume from 3D reconstruction. (d) The lattice displacement along the x-direction corresponding to panel (c). (e) Slice through the ε_zz volume from 3D reconstruction. (d) The corresponding lattice displacement along the z-direction.^[49]
