Niobium nitride based thin films deposited by DC reactive magnetron sputtering
Due to their high hardness, high melting point and high chemical stability, transition metal nitrides present a great interest for various applications. This work constitutes a contribution to the understanding of the properties of Nb based binary and tern ...
EPFL2005Strengthening mechanisms and thermal stability of arc deposited nanostructured TiAlN-based thin films
Titanium aluminium nitride (TiAlN)-based coatings are designed specially for applications where oxidation and wear resistance are primary demands, as in the case of cutting tools. Moreover the coatings are required to be thermally stable as well as have go ...
EPFL2004Direct observation of toughening mechanisms in carbon nanotube ceramic matrix composites
The excellent mechanical properties of carbon nanotubes (CNTS) are driving research into the creation of new strong, tough nanocomposite systems. Here, the first evidence of toughening mechanisms operating in carbon-nanotube-reinforced ceramic composites i ...
2004Chemical beam deposition of titanium dioxide thin films
Titanium dioxide (TiO2) is a widely investigated material for its biological compatibility, high dielectric constant and refractive index, chemical and mechanical resistance, and catalytic activity. Several different techniques are available to produce TiO ...
EPFL2003Mechanical analysis of ultrathin oxide coatings on polymer substrates in-situ in a scanning electron microscope
Uniaxial fragmentation tests were carried out in situ in a scanning electron microscope (SEM) on 10-nm-thick silicon oxide coatings deposited by plasma enhanced chemical vapor deposition on poly(ethylene terephthalate). In order to prevent charging effects ...
2003Durability of hybrid PECVD-based coatings on semicrystalline polymers
The present work analyses silicon oxide coated polyester films, with attention paid to the effect of substrate process additives on the coating defect population, and on the coated film mechanical properties. The defect population is characterized by means ...
2003Low-temperature thick-film dielectrics stabilised by reaction with a nanocrystalline powder
Peter Ryser, Thomas Maeder, Caroline Jacq, Sonia Vionnet Menot
In this work, a low-temperature thick-film dielectric consisting of a high-lead low-temperature glass with a reactive nanoscale filler is characterised to enable deposition of thick-film electronics onto substrates such as glass and metals (steel, aluminiu ...
2003Microstructure and growth modes of stoichiometric NiAl and Ni3Al thin films deposited by r.f.-magnetron sputtering
Intermetallic thin films of stoichiometric NiAl and Ni3Al have been deposited onto n-type silicon (100) and nickel (110) substrates using r.f.-magnetron co-sputtering. The morphology and crystal structure of the thin films have been studied by transmission ...
2000Chemisorption pathways and Si 2p core-level shifts for the interaction of spherosiloxane clusters with Si(100): Implications for photoemission in Si/SiO2 systems
Using a first-principles density functional approach, we investigate the chemisorption mechanism for the interaction of spherosiloxane (H8Si8O12) clusters on Si(100). Our transition state studies reveal that the chemisorption pathway with the lowest activa ...
2000Propriétés électriques et optiques de couches minces de WS2 et MoS2 en vue d'applications photovoltaïques
Single crystals of layered semiconductors such as WS2 and MoS2 have already proven their efficiency as active elements in photovoltaic cells. Due to their high optical absorption coefficient in the visible range, these materials could be used in the form o ...
