The TCV tokamak is equipped with a four-channel ultrasoft x-ray monochromator allowing low resolution (lambda/Deltalambda similar to 30) measurements in the energy range 200-800eV. Its main purpose is to simultaneously monitor emission from four of the mai ...
Using a first-principles approach, we study Si 2p core-level shifts at water and hydrogen covered Si(001)2 x 1 surfaces. After allowing for full relaxation of the surface structures, core-level shifts are calculated including core-hole relaxation effects. ...
The electronic properties were studied of TiO2 and electrochem. Li-inserted TiO2 using synchrotron radiation photoelectron spectroscopy and x-ray absorption spectroscopy (XAS) in conjunction with resonant photoelectron spectroscopy. Core level (Ti 2p) and ...
Networks-on-chip provide an elegant framework to efficiently reuse predesigned cores. However, reuse of cores is jeopardized by new deep sub-micron noise effects that challenge the reliability of CMOS technology. Moreover, noise margins are further reduced ...
Using a first-principles approach, we compare calculated core-level shifts with experimental data for amorphous carbon at different densities. We used a molecular dynamics approach based on an environmental-dependent tight-binding (EDTB) Hamiltonian to gen ...
Using a first-principles approach, we investigate the effect of interdimer interactions on N Is core-level shifts at the NH3 saturated Si(100)-2 X 1 surface. Fully relaxed model structures are generated in which -NH2 groups on adjacent dimers in a row are ...
Recent studies have shown that the hardware behavior of database workloads is suboptimal when compared to scientific workloads, and have identified the processor and memory subsystem as the true performance bottlenecks, when running decision-support worklo ...
Using a first-principles approach, we investigate nitrogen bonding configurations at nitrided Si(001) surfaces and Si(001)-SiO2 interfaces by comparing calculated core-level shifts with measured photoemission spectra. Fully relaxed model structures are gen ...
A first-principle approach allows the study of relaxed structural models for surfaces and interfaces. This is a powerful tool for the study of the local bonding. The utility of the first-principle theory is substantially extended through the calculation of ...
Using a first-principles approach, we study the incorporation of nitrogen at the Si(001)-SiO2 interface by calculating N Is core-level shifts for several relaxed interface models. The unusually large shift with oxide thickness of the principal peak in phot ...
