Dec 17, 2018
In situ transmission electron microscopy reveals that an atomically thin crystalline phase at the surface of liquid Au-Si is stable over an unexpectedly wide range of conditions. By measuring the surface structure as a function...
Electron and hole mobilities at a Si/SiO<sub>2</sub> interface with giant valley splitting
We examine the electron mobility and hole mobility at the Si/buried oxide (BOX) interface at which the valley splitting of the electron system is strongly enhanced, and compare the values observed to those at a standard...

Defects in TiO 2 films on p +-Si studied by positron annihilation spectroscopy
Variable-energy positron annihilation spectroscopy has been applied to the study of defects in TiO 2/p +-Si structures, in the as-grown state and after annealing in vacuum and in hydrogen, to investigate whether annealing (and...
Ge/Si and Ge Isotope Fractionation During Glacial and Non-glacial Weathering
Glacial environments offer the opportunity to study the incipient stages of chemical weathering due to the high availability of finely ground sediments, low water temperatures, and typically short rock-water interaction...
Exploration of the Semantic Difference between the Two Negative Markers lw- and (-)si(-) in Swahili
Christa Beaudoin-Lietz
Sep 05, 2013
When dealing with negation, grammars of Standard Swahili generally present three basic negative markers, ha-, (-)si(-), and -to-. For two of these three markers, ha- and -si-, grammars describe their distribution, but...

Face Dependence of Schottky Barriers Heights of Silicides and Germanides on Si and Ge.
Density functional supercell calculations of the Schottky barrier heights (SBH) of metal germanides and silicides on Si or Ge find that these vary with the facet, unlike those of elemental metals. In addition, silicides and...

A Classical Molecular Dynamics Study on the Effect of Si/Al Ratio and Silanol Nest Defects on Water Diffusion in Zeolite HY
The diffusion of water confined in zeolite HY has been studied using classical molecular dynamics at 300 K to probe the effects of water loading, Si/Al ratio, and silanol nest defect presence on the behavior of water confined...

Substantiation of buried two dimensional hole gas (2DHG) existence in GaN-on-Si epitaxial heterostructure
Gallium Nitride on Silicon (GaN-on-Si) devices feature a relatively thick epi buffer layer to release the stress related to the lattice constant mismatch between GaN and Si. The buffer layer is formed by several AlGaN-based...
