Selective control of fcc and hcp crystal structures in Au–Ru solid-solution alloy nanoparticles

Autor: Quan Zhang, Kohei Kusada, Dongshuang Wu, Tomokazu Yamamoto, Takaaki Toriyama, Syo Matsumura, Shogo Kawaguchi, Yoshiki Kubota, Hiroshi Kitagawa

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-9 (2018)

The crystal structure of a solid-solution alloy is generally determined by its elemental composition, limiting synthetic control over the alloy’s properties. Here, the authors are able to selectively control the crystal structure of Au–Ru alloy n
