When prepared by conventional evaporation or sputtering, thin films of amorphous silicon contain a large concentration of defects and microvoids.3,4 These give rise to localized states in the energy gap of the material.3,4 Plasma-enhanced chemical vapor deposition (PECVD), using silicon hydrides, significantly reduces the number of defects and thereby lowers the concentration of localized state...

The reliability of force fields is one of today's major challenges in atomic scale computer simulations. We show how to generate predictive force fields from ab initio simulations in the condensed phase, using maximally localized Wannier orbitals (WO). We derive separately all interaction terms (electrostatic, exchange repulsion, dispersion, and induction) from these localized WOs. We demonstra...

The purpose of this article is to present a rare case of localized, solitary amyloid tumor of tongue base and emphasize some of the characteristic features of challenging clinical and histopathologic diagnosis. In this paper, we focused on the clinical and pathological specifications of this rare tumor, so any unnecessary examinations or measures may be spared. Negative staining of amyloid mate...

Crack front waves are nonlinear localized waves that propagate along the leading edge of a crack. They are generated by both the interaction of a crack with a localized material inhomogeneity and the intrinsic formation of microbranches. Front waves are shown to transport energy, generate surface structure, and lead to localized velocity fluctuations. Their existence locally imparts inertia, wh...

Head on collision of localized waves in cold and dense hadronic matter with and without shear and bulk viscosities is investigated. Non-relativistic dynamics of propagating waves is studied using the hydrodynamics description of the system and suitable equation of state. It will be shown that the localized waves are described by solutions of the Burgers equation. Simulations show that the propa...

Sheet metal extrusion is a metal forming process in which the movement of a punch penetrates a sheet metal surface and it flows through a die orifice; the extruded parts can be deflected to have an extrusion cavity and protrusion on the opposite side. Therefore, this process results in a narrow region of highly localized plastic deformation due to the formation and microstructure effect on the ...

Hence it excludes proton decay and supersymmetry. The main predictions of a gauge model based on the exceptional simple Lie su-peralgebra mb(3|8) (a localized version of su(3) + su(2) + u(1)) are reviewed.

We report the carrier dynamics in GaAsSb ternary alloy grown by molecular beam epitaxy through comprehensive spectroscopic characterization over a wide temperature range. A detailed analysis of the experimental data reveals a complex carrier relaxation process involving both localized and delocalized states. At low temperature, the localized degree shows linear relationship with the increase of...

In this paper, the flexural behavior of High-performance Fiber-Reinforced Cementitious Composite (HPFRCC) has been investigated, especially focusing on the localization of cracks, which significantly governs the flexural behavior of HPFRCC members. From four points bending tests with HPFRCC members, it was observed that almost evenly distributed cracks formed gradually, followed by a localized ...

We examine various issues relevant to localization in the Anderson model. We show there is more to localization than exponentially localized states by presenting an example with such states but where 〈x(t)2〉/t2−δ is unbounded for any δ > 0. We show that the recently discovered instability of localization under rank one perturbations is only a weak instability. PACS: 72.15.Rn ∗This material is b...
