Size and shape of supported zirconia nanoparticles determined by x-ray photoelectron spectroscopy
(American Institute of Physics, 2007)
The initial stages of growth of zirconia nanoparticles deposited on SiO2, Y2O3, and CeO2 substrates have been studied by the x-ray photoelectron spectroscopy peak shape analysis. ZrO2 was deposited by plasma decomposition ...

Phase delay and group velocity determination at a planar defect state in three dimensional photonic crystals
(American Institute of Physics, 2007)
Phase sensitive optical transmission measurements have been performed on three dimensional opal-based photonic crystals containing a planar defect. From numerical derivation of the measured phase, the group velocity has ...
