Paper Abstract

Erosion and evolution of Ni and Cu(111) surface topography under impact of small N-atomic clusters (N=1÷55) with energies of 500 eV/atom is studied at atomic scale using a many-body potential. To provide final thermodynamics equilibrium state at non-zero (room) temperature, the Molecular Dynamics (MD) simulation was combined with statistical data sampling techniques in the frame of Metropolis Monte-Carlo (MMC) method. It was demonstrated that pronounced micro-crater surrounded by rim of ad-atoms is formed in the impact region above a threshold cluster size of around N=9. The impact of smaller clusters leads to formation of shallow craters or vacancies and ad-atom islands on a surface.
