Abstract

Bimetallic particles were formed by pulsed laser ablation of bulk AuCu in a vacuum and characterized by X-ray diffraction and transmission electron microscopy. The fcc-type AuCu3 and Cu-doped Au nanocondensates ca. 5 nm in size were coalesced over {001} and ~{111} vicinal surfaces to form quasi multiple twinned particles with solute/vacancy entrapped [110]{hkl} tilt boundaries with a symmetric {111}/{111} interface as well as asymmetric {001}/{111} and {331}/{112} interfaces. Polysynthetic {111} twinning due to strain relaxation and the shock effect was also observed for the alloyed particulates and nanocondensates.
