In the present work, a new way to obtain bimetallic nanoclusters of different structures and chemicalcompositions is proposed, which is based on computer simulations. Collision processes between twometal clusters of different natures are simulated through molecular-dynamics simulations usingmany-body potentials. Diverse diffusion mechanisms and structures can be observed, depending onthe metals combined and the initial kinetic energies. The nanostructures we have found arecore-shell Pt–Au, alloyed Pd–Au, and three-shell onionlike Cu–Ag.
