The irradiation of carbon based nanostructures with ions and electrons has been shown to be an appropriate tool to tailor their properties. The defects induced in the nanostructures during irradiation are able to modify their mechanical and electroni

Publikováno v: The European Physical Journal D. 59:209-213

We report the results of an experimental-theoretical study on the stopping power of ZrO2 films for swift H and He ion beams. The experiments, using the Rutherford Backscattering technique, were done for protons with incident energies in the range 200

The angular distributions of protons travelling through thin polycrystalline gold targets (15nm) with incident energies in the range of 4-10 keV have been measured. The results confirm previous experiments at higher energies showing deviations from t

Influence of electron capture and loss in the energy distribution of protons dissociated from fast H2+ molecules in carbon foils

Autor: Isabel Abril, Kenji Kimura, Manuel D. Barriga-Carrasco, Néstor R. Arista, C. D. Denton, Rafael Garcia-Molina

Publikováno v: physica status solidi (c). 1:S21-S25

We have measured and calculated the energy distribution at zero exit angle of the proton fragments resulting from the dissociation of fast H2+ molecules when traversing carbon foils of different thicknesses. We discuss the role played by several proc

Plasmon excitation by charged particles moving near a solid surface

Autor: R O Barrachina, J. L. Gervasoni, C D Denton, Néstor R. Arista

Publikováno v: Physical Review A. 57:4498-4511

The interaction of fast charged particles with a semi-infinite medium is described using both quantum-mechanical and semiclassical dielectric formulations. We consider the coupling with bulk and surface excitations for arbitrary trajectories of the p

Annealing of radiation damage in Si. A molecular dynamics study

Autor: C. D. Denton, A. Gras-Martí, V. Konoplev, J.J. Jiménez-Rodríguez

Publikováno v: Radiation Effects and Defects in Solids. 141:129-140

We investigate the annealing of damage produced by a dense collision cascade in the bulk of a silicon target. The evolution of the damage with time (up to 50ps) and its dependence with the annealing temperature (up to 1700 K) are studied. We find tha

We have studied the energy loss of protons in multi-walled carbon nanotube (MWCNT) samples, both experimentally and theoretically. The experiments were done in transmission geometry, using 6 and 10 keV proton beams, with the MWCNT targets dispersed o
