Resumen: | We study in detail, via experimental measurements, atomistic simulations, and density functional theory transport calculations, the process of formation and the resulting electronic properties of atomic-sized contacts made of Au, Ag, and Cu. Our data analysis of both experimental results and simulations leads to a precise relationship between geometry and electronic transmission—we reestablish the significant influence of the number of first neighbors on the electronic properties of atomic-sized contacts. This result allows us also to interpret subtle differences between the metals during the process of contact formation as well as the characteristics of the resulting contacts. |
