Key Points

The research aims to explore the 3D structure of a silver-rich supercluster and its growth process from nanoclusters to nanoparticles.
Characterization of a tetrahedral supercluster composed of iridium and silver icosahedra.
Analysis of vertex-sharing units within the supercluster structure.
The discovery highlights a new tetrahedral arrangement that facilitates the understanding of cluster dynamics.
Observations provide insights into the transition from nanoclusters to larger nanoparticle formations.

Implication

Reveals a tetrahedral supercluster structure composed of 8-electron iridium and silver, suggesting insights into cluster growth.

Abstract

units sharing six vertices to achieve the tetra-icosahedral kernel. The discovery of this 3D supercluster can more effectively help us understanding the growing process from nanoclusters to nanoparticles.
