In particular, we have shown that just having atoms of different size leads to a remarkable stabilization of polytetrahedral structures, including both polyicosahedral clusters and at larger sizes structures with disclination lines.5 pages, 5 figuresMaterials ScienceAtomic and Molecular Clusterstext
