Context. Gas-phase sodium, silicon, potassium, and calcium were previously identified in mass spectra recorded the coma of comet 67P/Churyumov-Gerasimenko, target European Space Agency’s Rosetta mission. The major release process for these atoms was as sputtering by solar wind. More recently, remote observations numerous comets over a range heliocentric distances revealed presence metal iron ni...

Indium-tin oxide films are deposited by low plasma temperature RF sputtering on highly flexible modification of glycol polyethyleneterephtalate substrates. The produced layers are characterized with transparency over 82 % and sheet resistance of 86.9 Ω/square. The film’s conductivity was further improved by additional UV illumination from light source (365 nm), having power of 250 W. The influe...

To ascertain the importance of sputtering by solar wind ions on the formation of a sodium exosphere around Mercury and the Moon, we have irradiated with 4 keV He ions, the Na bearing tectosilicates: albite, labradorite, and anorthoclase, as well as adsorbed Na layers deposited on albite and on olivine (a neosilicate that does not contain Na). Sodium at the surface and near surface (<40 Å) was q...

Silicon nanowires of various diameters were irradiated with 100 keV and 300 keV Ar(+) ions on a rotatable and heatable stage. Irradiation at elevated temperatures above 300 °C retains the geometry of the nanostructure and sputtering can be gauged accurately. The diameter dependence of the sputtering shows a maximum if the ion range matches the nanowire diameter, which is in good agreement with ...

Highly transparent and conducting fluorine-doped ZnO (FZO) thin films were deposited onto glass substrates by radio-frequency (RF) magnetron sputtering, using 1.5 wt% zinc fluoride (ZnF2)-doped ZnO as sputtering target. Structural, electrical, and optical properties of the FZO thin films were investigated as a function of substrate temperature ranging from room temperature (RT) to 300°C. The cr...

Argon cluster sputtering of an organic multilayer reference material consisting of two organic components, 4,4'-bis[N-(1-naphthyl-1-)-N-phenyl- amino]-biphenyl (NPB) and aluminium tris-(8-hydroxyquinolate) (Alq3), materials commonly used in organic light-emitting diodes industry, was carried out using time-of-flight SIMS in dual beam mode. The sample used in this study consists of a ∽400-nm-thi...

In this paper, molecular dynamics simulations were performed to study interactions between atomic H and SiC, silicon carbon surfaces were continuously bombarded by atomic H with different energies. The Tersoff-Brenner potentials were implemented. The simulation results show that with increasing incident energy, the retention rate of H atoms on the surface increases linerly. A large number of H ...

The absolute sputtering yields of D+, He+and r.r on solid, liquid lithium and liquid tinlithium have been successfully measured and modeled at low energies in the Ion-surface InterAction Experiment (IIAX). IIAX is used in this work to determine the dependence of Li erosion on the use of hydrogen isotopes to treat liquid metal surfaces of both liquid lithium and liquid tin-lithium. Earlier data ...

We find the spatially averaged sputter yield [Formula: see text] analytically for non-planar surfaces that have slowly varying surface heights text]. To begin, nonlocal effects like redeposition of sputtered material and secondary sputtering are neglected. show leading order corrections to proportional spatial averages The constants proportionality can be written in terms first second derivativ...

The angular-resolved sputtering yield of Be by D + was predicted and then measured. An ion beam at 100, 300, 500 and 700 eV from a Colutron ion source was focused onto S-65 C grade Be samples. The sample was exposed in situ to a 350 V dc D plasma to remove oxide, load the surface with D and more-nearly simulate the surface which would be found during steady-state fusion device operating conditi...
