“…A limited penetration depth and a large sputtering yield are believed to be responsible for the improved depth profiling capabilities of cluster beams, as the damage induced by projectile impact is immediately removed. While many theoretical studies have been reported for systems bombarded by small clusters, [10][11][12][13][16][17][18][20][21][22][23][24][26][27][28][29] much less is known about phenomena taking place during massive cluster bombardment. In pioneering experiments with massive glycerol clusters, Mahoney and co-workers have shown that desorption of large peptide and protein ions is possible.…”

Microscopic Insight into the Sputtering of Thin Polystyrene Films on Ag{111} Induced by Large and Slow Ar Clusters

Molecular dynamics computer simulations were employed to model the bombardment of Ag{111} covered with a monolayer of sec-butyl-terminated polystyrene tetramer (PS4) molecules by the impact of large and slow clusters. The investigated surface was bombarded with clusters composed of between hundreds to 29 000 Ar atoms having a very low kinetic energy per atom (0.1−40 eV). The sputtering yield of molecular species and their internal, angular, and kinetic energy distributions were analyzed. The simulations demonstrated quite clearly that the physics of ejection by these large and slow clusters is distinct from the ejection events stimulated by the popular SIMS clusters, C60, Au3, and SF5.

“…In such conditions, crystal structures of incident particles are completely destroyed. Initial structures were maintained in some cases of lower impact energies, 8,12,13,15) although the assumed particles in these studies are too small to observe particle fragmentation. 18) A larger particle with lower incident speed is necessary to simulate particle fragmentation in the AD process.…”

“…[7][8][9][10][11][12][13][14][15][16][17] Most of these studies deal with clusters or small particles composed of less than 2000 atoms at higher impact energies than 1 eV/ atom. In such conditions, crystal structures of incident particles are completely destroyed.…”

“…In addition to the differences in size and incident speed of the particle, previous studies [7][8][9][10][11][12][13][14][15][16][17] have different standpoint for the particle orientation. These studies do not pay attention to crystallographic orientation of the incident particle, therefore assumed particle orientations were not described or simply mentioned 8,12,13) as 'at random'.…”

Particle fragmentation and modification of crystallographic orientation in the aerosol-deposition process were investigated by molecular dynamics simulation. Atomistic models of bcc Fe and fcc Ni particles of 10 nm in diameter were subjected to collision to at substrates, and analyzed for their structural modification due to the impact. It was found that particle fragmentation takes place depending on both crystal structure and initial orientation of incident particles. Modification of crystallographic orientation were observed in both bcc and fcc particles and in bcc substrates. Microscopic mechanisms of particle fragmentation and orientation modification were found to be classified into three types, sliding, compression, and third phase generation, which are related to slip systems and relaxation of interface structures.

“…Recently, the interactions of metallic clusters with metal based targets were investigated for individual com binations of cluster and target materials in the framework of classic molecular dynamics [2][3][4][5]. However, compar ative analysis of these results is complicated due to the use of different interatomic interaction potentials and other model parameters when they are obtained.…”

Abstracts-The interaction process of low energy copper, silver and gold clusters of different sizes (13, 27 and 39 atoms) and different energies of translational motion (100, 200, and 400 eV) with a Cu(100) surface has been investigated in the framework of classic molecular dynamics. A comparative analysis of the processes of atomic mixing and adsorption layer (adlayer) formation has been performed for bombarding clusters of dif ferent types, sizes, and translational motion energies.
