a Scanning electron microscopy images of the dried supported gold crystals, showing well-defined cuboctahedric (top) and cubic (bottom) shapes. b 3D diffraction pattern obtained by rocking scans around the (111) Bragg peak of the cube. c 3D displacement field along the [111] direction with the black vector representing the q111 scattering vector. The facets orientations are shown. d Cross-section views of the internal displacement along the [111] direction. Scale bars, 30 nm.
