Classical dynamics simulation of projectile-surface interactions

Abstract

A public‐domain package of programs for the personal computer, the Simulation Kit (SK), has been developed for the simulation and visualization of collisions of low‐energy (<10 keV) atomic projectiles with solid target lattices. Possible applications of the SK include the simulation of ion scattering spectra, sputtering coefficients, reflection coefficients and projectile ranges. The simulation model used by the SK is based on classical dynamics, and uses a composite screened‐Coulomb/Morse pair potential to model interactions between particles in the target. The simulation model also incorporates inelastic scattering effects based on the Lindhard–Schiøtt–Scharff, Oen–Robinson and Shapiro–Tombrello models, respectively. The physical basis of the simulation model is described, and examples are provided of applications in ion beam analysis (ion scattering spectrometry, sputter yields).

Six decades of atomic collisions in solids

“…From the measurements on Cu we would expect a greater difference. Probably either the oxide layer on A1, or the higher Kr concentration in A1 compared with While early theoretical descriptions of these phenomena [23,24,27] involved adjustable parameters, more recent calculations by binary-collision [28] or molecular-dynamics [29] codes predict the main features directly with an error margin given by the adopted interatomic potential.…”

Microplasmas: A Review

“…Molecular dynamics simulations [104] utilize Newton's laws using the interatomic interaction potentials between all species to analyze the above interactions, however they are computationally very time consuming. …”

Fundamental limits on the z-resolution of ion beam patterning of magnetic multilayers

“…These systems were chosen as they not only represent actual materials used in magnetic multilayers, but also allow comparison between a mixing alloy system (Ni-Cu) and a demixing alloy system (Co-Cu), illustrating the importance of thermodynamic effects such as wetting and alloying. We used the Kalypso Molecular Dynamics package [1]. The repulsive part of the potentials are of the Ziegler-Biersack--Littmark (ZBL) screened Coulomb potential type.…”

“…The Cu-Cu, Ni-Ni and Cu-Ni potentials are taken from Ref. [1], the Co-Co and Co-Cu potentials are taken from Ref. [2].…”
