Abstract

The energetic surface reconstruction phenomena observed on bimetallic nanoparticle systems of AuPd and AuCu was analyzed. The phenomena was similar to a resolidification observed during the cooling process in lead clusters. These binary alloy nanoparticles showed the fivefold edges truncated, resulting in {100} facets on decahedral structures. It was shown experimentally and by computational simulations that this eutectic structure is favored in such nanoalloy system.
