Authors: de Lara-Castells, Maria Pilar Journal: SMALL STRUCTURES Publication date: 2024/06/30 DOI: 10.1002/sstr.202400147 Abstract: Current advances in synthesizing and characterizing atomically precise monodisperse metal clusters (AMCs) at the subnanometer scale have opened up new possibilities in quantum materials research. Their quantizied molecule-like electronic structure showcases unique stability, and physical and chemical properties differentiate them from [...]
