The appearance of atomic structures of nanoscopic dimensions, with new and interesting physical properties, requires revisiting various aspects of particle interaction with solid matter. For this p...

When atomic particles traverse solids they suffer energy losses due to elastic scattering from nuclei and excitation of electron–hole pairs. These are referred to as nuclear and electronic stopping...

The total sputtering yield of 6 nm thick polycrystalline tantalum films resulting from H2+ ion bombardment, at normal incidence, has been determined. For this purpose, we study the evolution of the...

In the scattering and stopping of heavy ions on a few surface layers in solids, contributions of the electronic and nuclear energy losses can become comparable. In this work we present a study of 0.6--5-keV Ar ion scattering on a Cu (100) surface. En

Carbon nanotube properties can be modified by ion irradiation; therefore it is important to know the manner in which ions deposit energy (how much and where) in the nanotubes. In this work, we have studied, experimentally and with a simulation code,

This progress report focuses on recent work on energy losses undergone by keV slow ions through crystals and on solid surfaces. We treat cases where strong corrugations of the electron density along ion trajectories occur and where an averaged electr

Results of a study of electronic energy loss of low keV protons interacting with multilayer graphene targets are presented. Proton energy loss shows an unexpectedly high value as compared with measurements in amorphous carbon and carbon nanotubes. Fu

Results of measurements of electronic energy loss for few keV protons and deuterons interacting with multi-walled carbon nanotubes are presented. Analyses of the energy loss distributions, for both type of ions, show a particular shape which is due t

Measurements of energy-losses and electron transfer processes in 1–4 keV fluorine ions and atoms scattering on clean and oxygen covered Ag(1 1 0) were studied. We report data for surface channeling conditions for different surface azimuths for the

In this work we present a study of the effect of oxygen adsorption on the energy loss of 4 keV hydrogen ions, which are scattered off an Ag (1 1 0) single-crystal surface with varying coverages of oxygen. In this case oxygen adsorption leads to an ad
