Al(110) has been studied for temperatures up to 900 K via ensemble density-functional molecular dynamics. The strong anharmonicity displayed by this surface results in a negative coefficient of thermal expansion, where the first interlayer distance decreas ...
Lead zirconium titanium oxide (PZT) thin films are used for their ferroelectric and piezoelectric properties. The composition of the PZT is very important for these properties, and may also be influenced by inter- diffusion with the bottom electrode, on wh ...
We have evaluated the structure of high-reflectivity InP/InGaAsP distributed Bragg reflectors grown by chemical-beam epitaxy at a growth rate of 3 mu m/h. Transmission electron microscopy combined with electron energy loss spectroscopy indicate lateral flu ...
The aim of this research project is to study the deposition of thermal atoms and small ionised clusters on well defined surfaces. For this, an installation has been developed at the Institut de Physique Expérimentale to produce mass selected ionic metal cl ...
The microstructure and chemical composition of sputtered thin films are strongly correlated with the deposition conditions. In the present work, we report the investigation of the film composition by electron probe microanalysis and photoemission experimen ...
Using 13C-chem. shifts as a probe for the electronic environment of carbon centers, triphenylphosphoniomethanide, the model case of a reactive phosphorus ylide, have much more zwitterion than PC double bond character. Triphenylphosphoniopropenide (tripheny ...
