In this work we study the frontal collision of protons with the carbon atoms of a graphene
surface with a low coverage of adsorbed potassium. It is aimed at the analysis of the effect of …

The dependence of the negative-ion fractions on incident energy and angle is reported for
8.5–22.5 keV F− ions scattered from a Si (100) surface at a fixed scattering angle of 38. The …

Abstract The experiment of 6.5–22.5 keV C−, O− and F− ions scattering on water covered Si
(111) surface has been performed. It is found that the positive-ion fraction is very low and …

Charge transfer on graphite, a typical substrate and one of the fusion first wall materials, is of
great importance in the plasma–wall interaction, thin-film growth, and surface catalysis. We …

We use secondary electron spectroscopy to probe the excited states of graphene adsorbed
on a Ni (111) surface. A fine structure directly related to the empty bands above the vacuum …

We report results of ion neutralization of low-energy positive He ions interacting with a
surface of highly oriented pyrolitic graphite as a function of the impinging energy. We found …

We present measurements of secondary electron emission from Cu induced by low energy
bombardment (1–5keV) of noble gas (He+, Ne+ and Ar+) and Li+ ions. We identify different …

At keV energies, many electronic processes contribute to the emission of secondary
electrons in the interaction of highly charged ions on surfaces. To unravel contributions …

An experimental study of 8.5–22.5 keV-energy C–, O–, and F–ion scattering from an HOPG
surface has been performed at a grazing scattering angle. For a given incident angle or …

We report on the experimental energy distributions of electrons emitted in the interaction of
slow ions and electrons with aluminium and with monolayer graphite deposited on a Ni …
