Overcoming Imaging Limitations: 4D‐STEM Pair Distribution Function for Resolving Structure of Supported Pt55 and Pt200 Clusters
Metallic clusters in the 2–200 atom range exhibit exceptional functional properties arising from their large fraction of under‐coordinated surface sites and quantum size effects. However, structural characterization of these clusters is challenging due to the absence of well‐defined periodicity and long‐range crystal s...
