ABSTRACT
This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book moves straight into a recap of the basic quantum theory of the atom, starting with the Schrodinger equation. This will be useful background for understanding how the mathematical theory leads to similar electronic shell structure in metal clusters. The book then covers the experimental evidence for superatomic shell structure in real metal clusters, with a distinction between the generic idea of ‘a metal’ and the range of actual metallic elements that can be used for their synthesis – with consequent changes in their adherence to simple models. It explores the practical use of superatoms in detail: first through considering the tunability of individual superatoms, and their interactions with each other to form superatomic molecules, and secondly through the consideration of their ability to self-assemble into nanostructured solid-state materials.
