Quasi unidimensional growth of Co nanostructures on a strained Au(111) surface

Abstract: 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 first one consists of the control of diffusion through the temperature of deposition. The second one consists of a first step of platinum seeding in the reconstruction, followed by cobalt deposition with nucleation on the platinum seeds. [Copyright &y& Elsevier]
