The freezing behavior of gold nanoclusters was studied by employing molecular dynamics simulations based on the semiempirical embedded-atom method. Investigations of the gold nanoclusters revealed that, just after freezing, ordered nanosurfaces with a fivefold symmetry were formed with interior atoms remaining in the disordered state. Further lowering of temperatures induced nanocrystallization of the interior atoms that proceeded from the surface towards the core region, finally leading to an…

Free energy approach to the formation of an icosahedral structure during the freezing of gold nanoclusters
The freezing of metal nanoclusters such as gold, silver, and copper exhibits a structural evolution. The formation of the icosahedral (Ih) structure is dominant despite its energetic metastability.
Formation of an icosahedral structure during crystallization of nickel nanoclusters
The crystallization of nickel nanoclusters is investigated using a molecular dynamics simulation with tight-binding potentials. The formation of a cluster structure depends on the cooling conditions.
Melting of icosahedral gold nanoclusters from molecular dynamics simulations.
TLDR
Molecular dynamics simulations show that gold clusters with about 600-3000 atoms crystallize into a Mackay icosahedron upon cooling from the liquid, and the average shape of the cluster is nearly spherical at melting.
Modeling the crystallization of gold nanoclusters-the effect of the potential energy function.
The crystallization dynamics of 5083 atom gold nanoclusters, which were quenched from the melt, were studied by molecular dynamics (MD) using the EAM 'Glue' and 'Force-matched' potentials to compare
Molecular Dynamics Simulations of Competitive Freezing in Gold Nanoclusters
Molecular dynamics simulations are used to study the competitive freezing of icosahedral, decahedral, polydecahedral, and face-centered cubic structures in gold nanoclusters for a range of cluster
On the problem of the formation of structural modifications in Ni nanoclusters
The processes of melting and crystallization of Ni nanoclusters with a diameter to 3.6 nm have been studied by the molecular-dynamics method based on tight-binding potentials. The effect of the
Formation of icosahedral and hcp structures in bimetallic Co–Cu clusters during the freezing processes
Abstract The formations of nanoclusters with different geometries are strongly related to the nucleation. This is of importance in controlling the structures of nanoclusters. In this letter, the
Freezing of gold nanoclusters into poly-decahedral structures
A new family of cluster structures is found by molecular dynamics freezing simulations of gold nanoclusters in the 2–4 nm size range. These clusters are poly-decahedra, characterized by having
Melting and equilibrium shape of icosahedral gold nanoparticles
Abstract We use molecular dynamics simulations to study the melting of gold icosahedral clusters of a few thousand atoms. We pay particular attention to the behavior of surface atoms, and to the
Topological characterization of crystallization of gold nanoclusters.
TLDR
The results support the hypothesis that crystallization is initiated from the surface and proceeds into the cluster core, and the structure measure used is based on planar graphs.
