Spatial distribution of excess free volume in the Voronoi-NG model as compared to FCC-NG models based on MG carved particles (MG-NG) and inert gas condensation generated particles (IGC-NG). (a)–(c) Distribution of atomic volume averaged in a spherical volume of 1 nm radius around each atom, normalized by the bulk MG averaged atomic volume. (d)–(f) Distribution of atoms with normalized atomic volume greater than 1.03. Images (d)–(f) created with OVITO version 3.5.3, https://www.ovito.org.
