Polyhedral ground states in clusters of asymmetric hard sphere ions.
Clusters of hard sphere ions with sufficient size asymmetry to stabilize a tetrahedral structure in the bulk are found to exhibit trivalent polyhedral ground states in clusters of up to roughly 200 ions. The map of cluster ground state structures over the space of cluster size and ion asymmetry is presented.
