Electron cyclotron resonance deposition, structure, and properties of oxygen incorporated hydrogenated diamondlike amorphous carbon films Thin films of titanium oxynitride were produced by ion assisted deposition of titanium using different nitrogen to oxygen ion ratios. X-ray, Raman, nuclear reaction analysis and Rutherford backscattering spectroscopies were used to study the film structure and to establish the relationship between deposition conditions, film composition, and electrical and optical properties of the films in the visible and infrared. This method of deposition appears to yield hard, amorphous, and uniform films with a restricted compositional range near the equistoichiometric composition. Nevertheless, variations in oxygen content of the films can result in changes in the electrical and optical properties that are sufficiently large to enable their use as selective surfaces.
This report takes all the available good quality quantal calculations of excitation cross-sections by electron collision for lithium-like ions and intercompares them. There is a comparison also with the small amount of experimental data of 2s %-2p aP cross-sections. On the basis of all of these data, a choice is made of the best cross-sections and these are integrated over Maxwellians to give excitation rate coefficients. In general data are available for up to seven transitions in five or six ions. When the results are compared along the iso-electronic sequence, trends are established which allow estimates to be made of the rate coefficients for these seven transitions for any lithium-like ion of nuclear charge greater than boron. The results are presented graphically and as simple formulae. The formulae reproduce the source data at various levels of accuracy from about f 1% for individual ions to universal formulae of accuracy better than f 15% in the relevant temperature ranges. The latter are contained on one page and represent an enormous condensation of the original source data without seriously compromising the authors' claimed accuracy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
