  • Dowd, Annette; Elliman, Robert; Luther-Davies, Barry (American Institute of Physics, 2001)
    The absorption and extinction spectra of Ge nanocrystals in silica formed by ion implantation are studied using photothermal deflection and transmission spectroscopies. It is found that scattering makes a significant ...
  • Dowd, Annette; Llewellyn, David; Elliman, Robert; Luther-Davies, Barry; Samoc, Marek; Fitz Gerald, John (Elsevier Inc, 2001)
    Ge nanocrystals formed in silica by implantation with 1.0 MeV Ge ions and subsequent annealing at 1100A?C were characterised by transmission electron microscopy and Raman spectroscopy. The nanocrystals were found to be ...
  • Hossain, A; Gentle, Angus; Smith, Geoff (American Institute of Physics, 2001)
  • Rahmani, Adel; Chaumet, Patrick; De Fornel, Frederique (American Physical Society, 2001)
    The modification of lifetime experienced by a fluorescent molecule placed in an arbitrary environment is investigated theoretically within the framework of linear response theory. We present a complete description of the ...
  • Ehle, M.; Shoutenkov, V.; Thierbach, M.; Harnett, J. I.; Haynes, R. F.; Sokoloff, D. D.; Beck, R.; Shukurov, A. (EDP Sciences, 2002)
  • Joseph, E. K; Franklin, J.; Smith, G. B; Deller, C. A (Causal Productions Pty Ltd, 2002)
    Flexible polymer light guides doped with special micro-spheres to combine light leakage and long distance transport are described optically using a simple light distribution model. A constant angular profile of light ...
  • Mikajlo, E. A.; Nixon, K. L.; Coleman, V. A.; Ford, M. J. (Institute of Physics Publishing, 2002)
    Using the technique of electron momentum spectroscopy (EMS) we have measured the oxygen 2p- and 2s-derived valence bands and lithium 1s-derived core level in lithium oxide. All three sets of bands have been measured in a ...
  • Orlic, I.; Siegele, R.; Menon, D.; Cohen, D.; Jeffree, Ross; Mcphail, D.; Sarbutt, A.; Stelcer, E.; Markich, Scott (Elsevier B.V., 2002)
    Nuclear milli and microprobes at the Australian Nuclear Science and Technology Organisation (ANSTO) were used to determine lead accumulation in native Australian plants and animals. Three species of eucalypt plants ...
  • Rahmani, Adel; Chaumet, Patrick; Bryant, Garnett (Optical Society of America, 2002)
    We present a new formulation of the coupled dipole method that accounts for local-field effects and is exact in the long-wavelength limit. This formulation also leads to improved accuracy of the description of light-scattering ...
  • Rahmani, Adel; Chaumet, Patrick; Bryant, Garnett (Optical Society of America, 2002)
    The local-field correction experienced by an interstitial impurity in a crystal with cubic symmetry is derived by use of a rigorous, self-consistent, semimicroscopic description of spontaneous emission in a microcavity. ...
  • Rahmani, Adel; Bryant, Garnett (American Physical Society, 2002)
    We present a general, semimicroscopic, self-consistent treatment of spontaneous emission for a two-level atom in a dielectric microcavity with arbitrary shape. Both lossless and absorbing media are considered. Our approach ...
  • Chaumet, Patrick; Rahmani, Adel; Nieto-Vesperinas, Manuel (American Physical Society, 2002)
    We present a detailed theoretical study of the recent proposal for selective nanomanipulation of nanometric particles above a substrate using near-field optical forces [P.C. Chaumet et al., Phys. Rev. Lett. 88, 123601 ...
  • Chaumet, Patrick; Rahmani, Adel; Nieto-Vesperinas, Manuel (American Physical Society, 2002)
    We propose a novel way to trap and manipulate nano-objects above a dielectric substrate using an apertureless near-field probe. A combination of evanescent illumination and light scattering at the probe apex is used to ...
  • Zalipaev, Victor; Movchan, Alexander; Poulton, Christopher; Mcphedran, Ross (Royal Society, 2002)
    A mathematical model has been constructed to describe elastic waves propagating in a two?dimensional solid containing a doubly periodic parallelogram array of circular holes. A multipole expansion method is employed which ...
  • Guenneau, Sebastien; Poulton, Christopher; Movchan, Alexander (Elsevier, 2002)
    This Note is devoted to the analysis of elastic waves conically propagating through a doubly periodic array of cylindrical channels. A new method, based on a multiple scattering approach, has been proposed to reduce the ...
  • Zalipaev, Victor; Movchan, Alexander; Poulton, Christopher; Mcphedran, Ross (Kluwer, 2002)
    We study the propagation of elastic waves in a two-dimensional solid containing a doubly periodic array of circular holes. The method of multipoles expansions is employed here, so that it takes into account a coupling ...
  • Zhang, Nong; Kirpitchenko, Inessa (Academic Press, 2002)
    This paper presents the concept of a vibration control system in which motions of a continuous structure with piezoelectric sensors/actuators can be suppressed (or activated) through transforming mechanical energy to ...
  • Bradby, Jodie; Kucheyev, Sergei; Williams, Jim; Wong-Leung, Jennifer; Swain, Michael; Munroe, Paul; Li, Gang; Phillips, Matt (American Institute of Physics, 2002)
    The mechanical deformation of wurtzite GaN epilayers grown on sapphire substrates is studied by spherical indentation, cross-sectional transmission electron microscopy (XTEM), and scanning cathodoluminescence (CL) monochromatic ...
  • Peterson, Vanessa; Hunter, Brett; Ray, Abhi; Aldridge, Laurie (Springer-Verlag, 2002)
    Ordinary Portland-cement clinkers were characterised using neutron and synchrotron powder diffraction. Rietveld analysis was performed using individual as well as combined data. Comparisons were made between phase ...
