The geometry of {001} surfaces of spinel (MgAl2O4) was investigated by first-principles simulations within density-functional theory (DFT). The calculations show that the structure relaxation or reconstruction occurs for a depth of about 0.5 nm. The

Publikováno v: Langmuir, 20(1), 145-149. American Chemical Society
The outermost atomic layer of perfluorinated thiol monolayers on gold and poly(tetrafluoroethylene) (PTFE) is analyzed by low-energy ion scattering. Absolute quantification of fluorine density in this layer was achieved after calibrating the fluorine

Do present 'charge transfer to the continuum' theories correctly describe the production of vi=ve electrons in ion beam-foil collisions?
Autor: W Meckbach, J W McGowan, K C R Chiu, H H Brongersma
Publikováno v: Journal of Physics B: Atomic and Molecular Physics. 10:3255-3270
The authors' study is designed to test whether or not existing 'charge transfer to the continuum' theory adequately explains the production of vi approximately=ve electrons resulting from 0.2-0.5 MeV H+ and H2 + ion bombardment of thin carbon foils;
