Secondary ion emission from sapphire single crystal has been studied experimentally and by means of computer simulation. The particular oscillations of secondary ion energy spectra and two specific maxima of O + and Al + ions were observed under irra

Molecular dynamic simulation has been used to study how the sputtering characteristics of metal polycrystals are dependent on the mass m 1 of bombarding ions of low-energy E 0 . The influence of target parameters on mass dependence of sputtering has

The change of Auger-electron emission from polycrystals of disordered ferromagnetic NiPd3 and Ni3Pd alloys, under ferro- to paramagnetic transition, has been studied experimentally. It has been shown that the intensity of the Auger-lines, which are f

A dual ion beam system has been used to produce hard nanocomposite TiN/Si3N4 coatings on silicon substrate. Mechanical properties have been determined by nanoindentation and tribological properties have been measured by nanoscratch testing. Nanoinden

A simple general model has been formulated to explain the composition of compound films during growth simultaneous with ion bombardment. The variables in this model are (a) the sticking probability of the background residual reactive gas in the film,

Microbial cells retained in surface defects on an inert substratum may pose problems in cross-contamination (food contact surfaces), and provide a focus for infection (medical devices). Although the type and degree of substratum surface roughness aff
