We investigated to which extent a uniaxially-strained Au(111) surface, thereby displaying linear reconstructions, may be used as a template for the growth of elongated nanostructures. Cobalt has been used as a deposition material, and two routes have been followed satisfactorily. The rst one consists in the control of diusion through the temperature of deposition. The second one consists in a rst step of platinum seeding in the reconstruction, followed by cobalt deposition with nucleation on the platinum seeds.
