A mechanistic-based understanding of corrosion is needed in order to predict aging characteristics and reliability of either electronic or structural components. Although it is well known that the presence of a halide such as Cl− is necessary for p

Secondary ion mass spectrometry (SIMS) has been used in conjunction with isotopic labeling to determine the extent and rate of passive film hydration on aluminum. The rates at which oxygen- and hydrogen-containing species migrate through the film hav

We have used ion channeling to examine the lattice configuration of hydrogen in Mg doped wurtzite GaN grown by metal organic chemical vapor deposition. Hydrogen is introduced by exposure to hydrogen gas or electron cyclotron resonance plasmas and by

Ion-beam irradiation and ion implantation were used to evaluate the influence of point defects and alloying elements on the sulfidation rate of copper films in atmospheric environments containing H 2 S. Low-energy ions from an oxygen plasma were used

This paper examines the correlation between mechanical properties and the density, phase and hydrogen content of deposited alumina layers, and compares them to those of sapphire and amorphous alumina synthesized through ion-beam irradiation of sapphi

Nanostructural characterization of amorphous diamondlike carbon (a-C) films grown on silicon using pulsed-laser deposition (PLD) is correlated to both growth energetic and film thickness. Raman spectroscopy and x-ray reflectivity probe both the topol

The ion implantation of He is examined as a means to form thermally stable cavities in GaAs. Room-temperature implantation of 2–10 × 10 16 He/cm 2 at 40 or 50 keV forms bubbles, but subsequent annealing at 250°C or above leads to exfoliation of t

The role of hydrogen in enhancing the photoluminescence (PL) yield observed from Si nanocrystals embedded in SiO{sub 2} has been studied. SiO{sub 2} thermal oxides and bulk fused silica samples have been implanted with Si and subsequently annealed in
