Noble-metal nanostructures on carburized W(110)

► Au, Ag and Cu nanostructures were prepared on R(15 x 12) and R(15 x 3) C/W(110). ► On R(15 x 12) always isotropic clusters are formed. ► On R(15 x 3) the anisotropy of the nanostructures is controlled by temperature. ► At intermediate temperatures Au deposition induces domain boundaries. ► Comparison with Au nanostructures as reported by Varykhalov et al. (Ref 1).
