    Notes: Abstract. High-quality epitaxial CeO2 thin films were obtained on Si(001) buffered with a yttria-stabilised zirconia layer by pulsed laser deposition. Although the best structural properties were achieved at high substrate temperature, high-quality epitaxy was obtained even at room temperature. Epitaxial growth at low temperature is promoted by the high kinetic energy of particles reaching the substrate. The oxygen pressure and target–substrate distance had a strong influence on the crystallographic structure and surface morphology in low-temperature deposition. This behaviour is attributed to a change in the kinetic energy of the particles, which was evaluated from the plasma expansion velocity determined by an intensified CCD camera. If a shock wave forms, a minimum substrate temperature of 550 °C is necessary for epitaxial growth.

    Room-temperature epitaxial growth of CeO2(001) films on YSZ buffered Si(001) substrates (1998)

    Notes: 2 (001) epitaxial thin films deposited on Si(001) with yttria-stabilized zirconia buffers have been obtained for the first time at room temperature by pulsed-laser deposition. The influence of oxygen pressure on the crystal quality of CeO2 was studied for the films deposited at 100 °C. The rocking curve full width at half maximum of the CeO2(002) peak for films deposited at room temperature and 100 °C was between 1° and 2°, for oxygen pressures below 3×10-2 mbar. The best crystal quality was obtained at around 3×10-3 mbar. Epitaxial growth at room temperature was confirmed by cross-sectional transmission electron microscopy. Scanning electron microscopy and atomic force microscopy revealed very smooth surfaces for oxygen pressure below 3×10-2 mbar, with rms roughness values around 0.3 nm over 5 μm×5 μm.

    Variation of the electric properties along the diaphysis of bovine femoral bone (1991)
    Springer
    Medical & biological engineering & computing 29 (1991), S. 441-446 
    Details
    ISSN: 1741-0444

    Notes: Abstract A preliminary study is presented of the variability of the electric properties, in the axial, tangential and radial directions, as a function of position in the diaphysis of a femoral bovine bone. The measurements were carried out at three frequencies: 100 Hz, 10 kHz and 1 MHz. It is shown that both the conductivity and the permittivity exhibit significant variations along the diaphysis, and increase in magnitude towards the epiphyses. From this study, the variation of the electric properties cannot be clearly and directly ascribed to the longitudinal variability of the total volumetric fluid content of the bone. The results reflect the orthotropic nature of the electric properties, at any given location, and indicate a position-dependent tendency towards axis symmetry.
