An icosahedral twin is a nanostructure appearing for atomic clusters. These clusters are twenty-faced, made of ten interlinked dual-tetrahedron (bowtie) crystals, typically joined along triangular (e.g. cubic-(111)) faces having three-fold symmetry. One can think of their formation as a kind of atom-scale self-assembly.

has abstract	An icosahedral twin is a nanostructure appearing for atomic clusters. These clusters are twenty-faced, made of ten interlinked dual-tetrahedron (bowtie) crystals, typically joined along triangular (e.g. cubic-(111)) faces having three-fold symmetry. One can think of their formation as a kind of atom-scale self-assembly. A variety of nanostructures (e.g. condensing argon, metal atoms, and virus capsids) assume icosahedral form on size scales where surface forces eclipse those from the bulk. A twinned form of these nanostructures is sometimes found to occur e.g. in face-centered-cubic (FCC) metal-atom clusters. This may occur when the building blocks beneath each of the 20 facets of an initially icosahedral cluster (which cannot fill space without defects) "make the case" (as the surface-to-volume ratio of these facets decreases with size) for conversion to a translationally symmetric (e.g. defect-free face-centered-cubic) crystalline form (en)
