A family of TiO2–Al2O3 multilayers (Λ=2–72nmTiO2∕7nmAl2O3) is sputter deposited on fused silica substrates, sequentially annealed at 973 and 1273K, and analyzed by x-ray diffraction. The goal is to examine crystallization behavior upon anneali

Vitreous titania films with rutile short-range order were sputter deposited on unheated fused silica substrates, sequentially annealed at 973 and 1273 K, and examined by Raman microscopy, scanning electron microscopy, and x-ray diffraction. A segrega

The subject of this article is control of perforated pit growth in 316L stainless steel by application of an artificial overlayer film. The protection afforded by 250 nm thick films with two ZrO2–Al2O3 nanolaminate architectures, single-layer ZrO2,

The near-ultraviolet fundamental optical absorption edge of sputter-deposited ZrO2–TiO2 nanolaminate films on SiO2 substrates was studied by transmission-reflection spectrophotometry. Seven different bilayer architectures were investigated, with no

The polarization-dependent optical response of vitreous titanium dioxide films was determined by infrared reflection–absorption spectroscopy (IRAS). The predominant nearest-neighbor coordination (short-range order) in the films was characteristic o

Resonant Ultrasound Spectroscopy (RUS) of a spherical sample in a pressurizing gas atmosphere was investigated experimentally and theoretically. Measurements were made on a fused silica sphere in He, Ar, and N2 gases up to pressures of 120 bar. The p

The pressure dependence of the resonance frequency of several resonant ultrasound spectroscopy modes in a sample of fused silica has been measured at UCLA in atmospheres of air, helium, and argon near ambient temperature. For both compressional and t

Landauer's classic 1957 paper on electron transport in the presence of localized scatterers has provided a powerful approach for analysing the local transport field and the driving force for electromigration in metals. This approach leads to local fi

The high-frequency optical absorption edge of pure tetragonal ZrO2, isolated in a ZrO2–Al2O3 nanolaminate film structure, was determined using transmission spectrophotometry. The functional dependence of the absorption coefficient on photon energy

It is shown that electromigration‐induced open‐circuit failures of completely passivated polycrystalline metallizations in integrated circuits under normal operating conditions can be controlled by lattice diffusion rather than grain‐boundary d
