Journal ArticleDOI
Valence Band Photoemission Spectroscopy of a Ternary Layered Semiconductor - Znin2s4
TL;DR: In this paper, the authors show that an overall understanding of the electronic states in complex structures can be achieved by an approach based on photoemission experiments and chemical bonding considerations which has been widely used in the past to study simple binary layer compounds.
Journal ArticleDOI
Structure and electrical properties of sputtered lead titanate thin films
TL;DR: In this paper, lead titanate (PbTiO3) thin films have been deposited on silicon, platinum-coated silicon and titanium silicide by RF-magnetron sputtering from pressed powder targets.
Journal ArticleDOI
Influence of Ge addition on the morphology and properties of TiN thin films deposited by magnetron sputtering
Cosmin S. Sandu,Rosendo Sanjines,M. Benkahoul,Magdalena Parlinska-Wojtan,Ayatollah Karimi,Francis Lévy +5 more
TL;DR: In this paper, a ternary composite system was used to extend the knowledge about the formation of nanocomposite films, and the results showed that the segregation of Ge atoms to the TiN crystallite surface appears to be responsible for limitation of crystal growth and formation of a TiGe y amorphous phase.
Journal ArticleDOI
Density-of-States Changes near the Fermi Level and the Lattice Instability in Tise2
Giorgio Margaritondo,Carlo Maria Bertoni,J. H. Weaver,Francis Lévy,N. G. Stoffel,A. D. Katnani +5 more
TL;DR: In this article, the density of states changes near the Fermi level associated with the charge-density-wave-like lattice instability in Ti${\mathrm{Se}}_{2} have been observed.
Journal ArticleDOI
Photoemission broadening of Fermi-liquid systems, and its relevance to high-temperature superconductors.
Yeukuang Hwu,Luca Lozzi,S. La Rosa,Marshall Onellion,P. Alméras,F. Gozzo,Francis Lévy,Helmuth Berger,Giorgio Margaritondo +8 more
TL;DR: The results indicate that the broadening is primarily affected by extrinsic factors rather than by the lifetime-and also that the "anomalous" broadening of the photoemission spectra found for the normal state of the high-temperature superconductors cannot be automatically interpreted as evidence of non-Fermi-liquid behavior.
