Molecular-dynamics study of collision, implantation, and fragmentation of Ag7 on Pd(100).
نویسندگان
چکیده
By using embedded-atom-method interatomic potentials and molecular-dynamics simulations, we study the collision of a single Ag7 cluster on the Pd~100! substrate, at impact energies in the direction perpendicular to the ~100! surface E1520 eV ~2.86 eV/atom! and E2595 eV ~13.6 eV/atom!. Our results indicate that implantation occurs at both impact energies, but it is more important at E2 . As opposed to what is shown experimentally, little fragmentation takes place for E1 , while the calculated cluster fragmentation is in good agreement with the experimental data for E2 . @S0163-1829~96!08224-0#

Deposition of metallic clusters on a metallic surface at zero initial kinetic energy: Evidence for implantation and site exchanges
We have investigated the deposition at zero impact kinetic energy of the Ag atom and clusters (Ag7 ,Ag19) on the ~100! and ~111! surfaces of Pd by molecular-dynamics simulations performed within the embeddedatom-method scheme. Our results elucidate the role played by the adsorption energy in determining the final morphology of the cluster/substrate system when ideal nondestructive deposition co...
متن کاملMorphology and evolution of size-selected metallic clusters deposited on a metal surface: Ag19
We study size-selected deposition of Ag19 1 clusters on Pd~100! at total kinetic energies of 20 and 95 eV using thermal energy atom scattering and molecular-dynamics simulations. Contrary to the case of Ag7 where fragmentation is crucial to explain the data, the deposition leads at low temperature to noncompact structures localized around the impact point. We propose a model in which morphology...
متن کاملSize Dependence of the Elastic Properties of Pd Nanowire: Molecular Dynamics Simulation
The mechanical properties including elastic stiffness constants as well as bulk modulus of Palladium (Pd) nanowire were calculated in the constant temperature and pressure (NPT), ensemble by molecular dynamics (MD) simulation technique. The quantum Sutton-Chen (Q-SC) many-body potential was used to calculate the cohesive energy as well as forces experience by every atoms. The temperature and pr...
متن کاملMolecular Dynamics Simulation of Al Energetic Nano Cluster Impact (ECI) onto the Surface
On the atomic scale, Molecular Dynamic (MD) Simulation of Nano Al cluster impact on Al (100) substrate surface has been carried out for energies of 1-20 eV/atom to understand quantitatively the interaction mechanisms between the cluster atoms and the substrate atoms. The many body Embedded Atom Method (EAM) was used in this simulation. We investigated the maximum substrate temperature Tmax and...
متن کاملScaling relations for implantation of size-selected Au, Ag, and Si clusters into graphite.
The deposition of size-selected clusters represents a new route to the fabrication of truly nanometer-scale surface architectures, e.g., nanopores. We report a systematic experimental study, coupled with molecular dynamics simulations, of the implantation depths of size-selected Au7, Ag7, and Si7 clusters in the model graphite substrate. For impact energies between 1.0 and 5.5 keV, we find that...
