This short review discusses the concept of the electronic shell
structure in the context of metal nanoclusters. Electronic shell
structure is a natural consequence of quantization of fermionic
states in a quantum confinement, where the symmetry of
the confining potential creates energetically close-lying sets
of states that reflect the symmetry of the potential. It was
introduced in cluster physics in early 1980s and initially
influenced greatly by the related model of nuclear shell
structure from 1950’s. Three application areas are discussed
consisting of free gas phase clusters, clusters supported by
insulating oxides or oxide thin films, and clusters that are
synthesized by wet chemistry and stabilized by an organic
ligand layer. In all these systems, the concept of electronic
shell structure has turned out to be useful to organize a vast
amount of observations on abundance, stability, chemical
reactivity and optical properties. Although this review focuses
on theoretical concepts and computational results, relevant
experiments are discussed as well.

Stability, electronic structure, and optical properties of protected gold-doped silver Ag29-xAux (x = 0-5) nanoclusters
Juarez Mosqueda, Rosalba; Malola, Sami; Häkkinen, Hannu (The Royal Society of Chemistry, 2017)In this work, we used density functional theory (DFT) and linear response time-dependent DFT (LR-TDDFT) to investigate the stability, electronic structure, and optical properties of Au-doped [Ag29−xAux(BDT)12(TPP)4]3− ... -
Analysis of the Electronic Structure of Non-Spherical Ligand-Protected Metal Nanoclusters : The Case of a Box-Like Ag67
Juarez Mosqueda, Rosalba; Kaappa, Sami; Malola, Sami; Häkkinen, Hannu (American Chemical Society, 2017)In this work we introduce a new strategy to investigate the electronic shell structure of ligand-protected metal nanoclusters of polyhedral core shape. The central idea is to identify the symmetry of the Kohn–Sham molecular ... -

Density functional studies of the electronic structure and catalytic properties of small bare and ligand-protected gold clusters
Kacprzak, Katarzyna Anna (University of Jyväskylä, 2010)In this thesis, bare and thiolate-protected gold nanoclusters and thiolated polymeric gold, silver and copper complexes are computationally studied by using density functional codes GPAW (grid projector augmented wave) ... -
Magnetically induced currents and aromaticity in ligand-stabilized Au and AuPt superatoms
López-Estrada, Omar; Zuniga-Gutierrez, Bernardo; Selenius, Elli; Malola, Sami; Häkkinen, Hannu (Nature Publishing Group, 2021)Understanding magnetically induced currents (MICs) in aromatic or metallic nanostructures is crucial for interpreting local magnetic shielding and NMR data. Direct measurements of the induced currents have been successful ...
