    In capacitance-voltage (C-V) measurements, frequency dispersion in high-k dielectrics is often observed. The frequency dependence of the dielectric constant (k-value), that is the intrinsic frequency dispersion, could not be assessed before suppressing the effects of extrinsic frequency dispersion, such as the effects of the lossy interfacial layer (between the high-k thin film and silicon Cited by: A novel torsion/bending element for dynamic relaxation modeling Michael R.

      The problem of relaxation of the charge injected into a dielectric film has been analytically solved taking into account its conductivity and carrier trapping by both bulk and surface deep traps with fast (almost instantaneous) charging and finite discharge rates. The charge behavior in one-zone and two-zone relaxation modes has been by: 1. @article{osti_, title = {Effect of thermal annealing on the properties of transparent conductive In–Ga–Zn oxide thin films}, author = {Li, Ling and Fan, Lina and Li, Yanhuai and Song, Zhongxiao and Ma, Fei and Liu, Chunliang}, abstractNote = {Amorphous In–Ga–Zn oxide (IGZO) thin films were prepared using radio frequency magnetron sputtering at room : Li, Ling.

    sample (thin-film on quartz substrate), which on absorption produces a thermal gradient near the sample surface via non-radiative relaxation induced heating. This results in a refractive index gradient in the area surrounding the sample surface (the sample is immersed in a Fluorinert FCA72 high refractive index gradient inert liquid). The absence of conformational (torsional) relaxation is attributed to the small dihedral angle between monomers that is predicted for the stereoregular polymer in the ground state. Below −10 °C, the polymer forms excimer-like aggregates, showing vibrational structured absorption and emission bands similar to those observed in thin by:

The effect of a surface oxide film on torsional relaxation by Burton I. Edelson Download PDF EPUB FB2

The effect of a surface oxide film on the torsional relaxation of polycrystalline cadmium wires was investigated. The phenomenon of reversal when the film is removed during relaxation, known as the abnormal after-effect, is shown to be a reproducible effect directly dependent on the presence and elastic properties of a surface by: 9.

The near-surface oxidation-induced lattice relaxation and compositional changes of FeNi alloy nano-particles are investigated. Using a newly developed transfer system, the particle structure was characterised by means of aberration-corrected HR-TEM prior to exposing the particles to ambient air.

This allows for a comparison of oxidised and un-oxidised particles, by: 8. The influence of surface phenomena on relaxation rates was studied. Relaxation rates of clean wires were not influenced by the surrounding media; air, distilled water and dilute sulfuric acid. Relaxation rates of wires which had an oxide surface film were greater than those of the clean wires, and application of acid to oxidized wires caused reversals in the strain versus log time relaxation : Burton I.

Edelson. Coverage by surface oxide film species has a major effect upon the electrode kinetics of Cl 2 evolution and this is associated with large changes in the adsorption pseudocapacitance and coverage of the ‘overpotential deposited’ Cl˙ intermediate.

Surface effects. One usually observes faster relaxation rates for fluids inside a solid porous structure than for bulk fluids. This can be described as a surface relaxation effect, two or three fluid molecular layers having a specific relaxation rate much shorter than the bulk value.

The origin of this shorter relaxation rate, for most mineral materials like rocks, is the presence of paramagnetic centres. Glass Surfaces covers the proceedings of the Fourth Rolla Ceramic Materials Conference on Glass Surfaces.

The book presents 38 papers that are organized according to their respective theme. The text first covers the structure of subsurface layers and their role in glass technology, and then proceeds to discussing surface characterization and.

Cracking in the nanoscale native oxide film (Figure 6) has a negligible effect on a macroscopic sample of silicon under load since cracks of size a in the oxide could never reach the critical size, i.e., a c ≫h o, where h o is the native oxide thickness.

In contrast, the surface-to-volume ratio is far larger in micro- and nanoscale samples.

Studying nanoparticles with sizes varying from to nm, we show that surface relaxation occurs on a typical length of about 1 nm in the vicinity of surfaces.

Surface stress effects (Important for very thin films ~ islands) Note: Difference between surface energy and surface stress for solids.

• Surface energy γ: Reversible work required to create a unit area of a surface at constant temperature, volume and chemical potential. A combination of compressive uniaxial surface stress and torsional surface stress contributes to the mechanical behavior of silicon nanowires.

Depending on the reactivity of the metal concerned, further exposure at low temperatures may result either in a progressive conversion of the bulk material to oxide or the oxidation process may effectively stop after the formation of a passivating surface oxide film of a specific thickness (e.g.

Al). For exp. values of Gm,1=N/m, we indeed obtain Gm,2= N/m for the observed value of the surface tension of the oxide. Of course, a more interesting question.

The influence of size effects on the properties of nanostructures is subject of this book. Size and interfacial effects in oxides, semiconductors, magnetic and superconducting nanostructures, from very simple to very complex, are considered. The most general meaning is assumed for size effects.
