We report on a systematic study of the implantation of size-selected Ag N + clusters on a graphite sample, for different cluster sizes (N = 1,3,7,9,13) and different impact energies (E = 1-30 keV). Results show that the implantation depth scales line

The structure and the phase transitions of Xe, Kr and Ar physisorbed on Pt(1 1 1) in the submonolayer-coverage range has been explored by low-temperature scanning tunneling microscopy. The hexagonal incommensurate rotated (HIR) → hexagonal incommen

A beam of Pb clusters is produced with the inert gas aggregation method and probed by electron diffraction. Analysis of the diffraction patterns indicates that average cluster size can vary between 3 and 7 nm, according to nucleation conditions. The

Mass selected Ag 7 clusters have been deposited at two different impact energies (20 and 95 eV) on a dislocation network formed by evaporating 2 ML of Ag on Pt(1 1 1). The surface has been investigated by low temperature STM as a function of annealin

We study size-selected deposition of Ag/sub 19//sup +/ 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 Ag/sub 7/ where fragmentation is cru

Mass selected Ag/sub n/ clusters (n=1,7,19) from a secondary ion source have been deposited onto a Pt(111) substrate at low temperature. The surface and resulting cluster morphology have subsequently been characterized within the same UHV chamber by

We study the deposition and the very first steps of nucleation and growth of Ag on Pd(100) with thermal energy atom scattering. This technique is a very sensitive and nonperturbing probe to surface point defects, which permits an in situ and in-time
