Abstract: A cluster is a new type of microscopic material with properties that lie between atoms, molecules and macroscopic condensed matter. It has a definite number of atoms as well as a precise and controllable geometric and electronic structure. Some special clusters can be regarded as "superatoms" because their properties are similar to individual atoms, which can provide infinite possibilities for material assembly and device design at the atomic level. Taking fullerene clusters, metal-doped Si/Ge clusters, octahedralM₆E₈ clusters and As clusters as representatives, this perspective focuses on the recent experimental and theoretical studies of cluster-assembled structures, discusses the manipulation of their physical and chemical properties, and presents some prospects on the current challenges and future directions in this field.
