Strained Siand SiGe-based heterostructure MOSFETs grown on relaxed SiGe virtual substrates exhibit dramatic electron and hole mobility enhancements over bulk Si, making them promising candidates for next generation CMOS devices. The most heavily investigated heterostructures consist of a single strained Si layer grown upon a relaxed SiGe substrate. While this configuration offers significant pe...

convexity theory and duality theory are important issues in math- ematical programming. within the framework of credibility theory, this paper rst introduces the concept of convex fuzzy variables and some basic criteria. furthermore, a convexity theorem for fuzzy chance constrained programming is proved by adding some convexity conditions on the objective and constraint functions. finally,...

Tetrabromo aromatics can be synthesized by the Fischer-Zimmermann condensation of appropriate pyrylium salts with arylene dicarboxylic acid salts. Their cyclization intramolecular Yamamoto coupling yields strained bicyclophanes adjustable sizes and different intraannular bridges. All compounds adsorb at solid/liquid interface on highly oriented pyrolytic graphite (HOPG) are investigated scannin...

A series of alkene bearing small molecules were electrografted to the surface carbon fibers using in situ generation aryldiazonium salts. These used as an anchoring point for use Ring Opening Metathesis Polymerization (ROMP) a ‘graft from’ approach fiber modification. After modification, evaluation these modified epoxy resin, single fragmentation test, showed significant increases interfacial s...

The growth of pseudomorphically strained GaAs1 ySby layers with high Sb-mole fractions of yX0.35 are desired on GaAs substrates for making lasers and detectors in the mid-infrared range. The effect of gas-phase precursor chemistry on the strained-layer Sbincorporation efficiency in metalorganic vapor phase epitaxy (MOVPE) was determined using four combinations of ethyland methylGa and Sb precur...

This article discusses the growth of silicon and related materials using ultra-high vacuum chemical vapor deposition (UHV/CVD). This growth technique is well suited for deposition of strained epitaxial layers and also layers with metastable concentrations of impurities such as boron and carbon. In UHV/CVD, growth kinetics and the incorporation of various atoms other than silicon are determined ...

It is important to be able to determine anger and its degree for dialog management in an interactive speech interface. We investigated the characteristics of a strained rough voice as a conveyer of a speaker’s degree of anger. In hot anger speech in Japanese, a rough voice with high glottal tension is observed frequently, and the rate of occurrence of the strained rough voice increases accordin...

For epitaxial films, a critical thickness (tc) can create a phenomenological interface between a strained bottom layer and a relaxed top layer. Here, we present an experimental report of how the tc in BiFeO3 thin films acts as a boundary to determine the crystalline phase, ferroelectricity, and piezoelectricity in 60 nm thick BiFeO3/SrRuO3/SrTiO3 substrate. We found larger Fe cation displacemen...
