Three-dimensional atomic-scale structure of size-selected gold nanoclusters

Abstract:
An unambiguous determination of the three-dimensional structure of nanoparticles is challenging1. Electron tomography requires a series of images taken for many different specimen orientations2. This approach is ideal for stable and stationary structures3. But ultrasmall nanoparticles are intrinsically structurally unstable and may interact with the incident electron beam4, 5, 6, constraining the electron beam density that can be used and the duration of the observation. Here we use aberration-corrected scanning transmission electron microscopy7, coupled with simple imaging simulation, to determine with atomic resolution the size, three-dimensional shape, orientation and atomic arrangement of size-selected gold nanoclusters that are preformed in the gas phase and soft-landed on an amorphous carbon substrate.
