摘要: The self-assembling of Au nanoparticles into nanowires different structure has been investigated by means a periodic approach within density functional theory using an Au79 nanoparticle as building block. calculations show that the interaction takes place preferentially along [111] direction, in agreement with experimental. electronic studied is found to be intermediate between isolated and bulk metal. This perhaps not surprising but important consequences for chemistry such nanostructures. Finally, carried out built from Cu, Ag containing 38 atoms reveal mechanism general strength dictated chemical nature metal being coinage leading stronger nanoparticles.
