  • 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 ...
  • Gauvin, Ranald; Griffin, Brendan; Nockolds, Clive; Phillips, Matthew; Joy, David (Wiley, 2002)
    A simple method is described to determine the effective gas path length when incident electrons scatter in the gas above the specimen. This method is based on the measurement of a characteristic x-ray line emitted from a ...
  • 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 ...
  • 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 ...
  • Johnston, Michael; Corchia, A; Dowd, Annette; Linfield, Edmund; Davies, A.; Mclaughlin, Robert; Arnone, Don; Pepper, Michael (Elsevier, 2002)
    We discuss the origins of the magnetic-field-induced enhancement of terahertz (THz) emission from bulk semiconductor surfaces. The principal effect of the magnetic field is to rotate the THz dipole and hence dramatically ...
  • Mcphedran, Ross; Nicorovici, Nicolae; Mckenzie, David; Rouse, Greg; Botten, Lindsay; Welch, Victoria; Parker, Andrew; Wohlgennant, M; Vardeny, Zeev (Elsevier Science Bv, 2003)
    We discuss two examples of living creatures using photonic crystals to achieve iridescent colouration. The first is the sea mouse (Aphroditidae, Polychaeta), which has a hexagonal close packed structure of holes in its ...
  • Ton-That, Cuong; Shard, Alex; Egger, S.; Taninaka, Atsushi; Shinohara, Hisanori; Welland, Mark (Elsevier Inc, 2003)
    The growth of endohedral fullerene La@C82 films on Si(1 1 1) has been explored by scanning tunneling microscopy (STM). The STM images reveal the molecules are hexagonally close-packed in multilayer films with the inter-molecular ...
  • Ton-That, Cuong; Shard, Alex; Egger, S.; Dhanak, Vinod; Taninaka, Atsushi; Shinohara, Hisanori; Welland, Mark (American Physical Society, 2003)
    The orientation of the endohedral La atom in La@C82 adsorbed on Cu(111) has been determined using the normal-incidence x-ray standing wave (NIXSW) technique. The NIXSW measurements were carried out using both the normal ...
  • Hodgkinson, Ian; Wu, Qi; De Silva, Lakshman; Arnold, Matthew; Mccall, Martin; Lakhtakia, Akhlesh (American Physical Society, 2003)
    We consider the circularly polarized localized modes of chiral photonic structures with combined central twist and isotropic layer defects. The general filter is shown to suffer from anomalous remittance and saturation of ...
  • Godlewski, Marek; Guziewicz, Elzbieta; Kopalko, Krzysztof; Lusakowska, Elzbieta; Dynowska, Elzbieta; Goldys, Ewa; Phillips, Matthew (Elsevier Science Bv, 2003)
    We discuss light emission properties from thin films of ZnSe grown by atomic layer epitaxy on GaAs (1 0 0). White color emission is observed in photoluminescence and cathodoluminescence, due to the observation of three RGB ...
  • Ton-That, Cuong; Shard, Alex; Egger, S.; Dhanak, Vinod; Welland, Mark (American Physical Society, 2003)
    The photon-energy dependences of valence-band photoemission spectra have been investigated for monolayer, submonolayer, and multilayer C60 films on Ag(111). The intensity ratios of the highest and next-highest occupied ...
  • Solina, Danica; Cheary, Robert; Swift, Paul; Mccredie, Geoffrey (Elsevier Science Sa, 2003)
    An investigation has been carried out to determine the conditions required for the fabrication of stable SiO2?Pt multilayers using DC-magnetron sputtering for the Pt and RF-magnetron sputtering for the SiO2. As a preliminary ...
  • Smith, Geoff; Botten, Lindsay; Mcphedran, Ross; Nicorovici, Nicolae (American Physical Soc, 2003)
    We use our previous formulation for cylinder gratings in conical incidence to discuss the photonic band gap properties of woodpile structures. We study scattering matrices and Bloch modes of the woodpile, and use these ...
  • Mcdonagh, Andrew; Clays, Koen; Persoons, Andre; Asselberghs, Inge; Ward, Michael; Mccleverty, Jon (Elsevier Limited, 2003)
    In situ reversible electrochemical switching of the molecular second-order nonlinear optical (NLO) polarizability, or first hyperpolarizability, has been implemented in a specially designed cell. The redox-switchable NLO ...
  • Yatsunenko, S; Khachapuridze, A; Ivanov, V Yu; Godlewski, M; Khoi, Le Van; Golacki, Zbigniew; Karczewski, Grzegorz; Goldys, Ewa; Phillips, Matthew; Klar, Peter; Heimbrodt, Wolfram (Polish Academy of Sciences Institute of Physcis, 2003)
    Based on the results of optically detected magnetic resonance and time-resolved investigations we relate the observed lifetime shortening of intra-shell Mn2+ emission to spin dependent magnetic interactions between localized ...
  • Gelhausen, Olaf; Klein, Hn; Phillips, Matthew; Goldys, Ewa (Wiley-v C H Verlag Gmbh, 2003)
    In-plane- and depth-resolved cathodoluminescence (CL) microanalysis and spectroscopy was carried out to study the impact of electron injection on electro-migration and diffusion of native defects and residual impurities ...
  • Chung, Kwok; Sanagavarapu, Ananda (John Wiley & Sons Inc, 2003)
    In this paper, we investigate the effect of the offset patch and layer misalignments on the broadband characteristics of a two-layer, electromagnetically coupled, stacked patch antenna with airgap at the X-band. Linear and ...
  • Sotelo, J.; Ederth, J.; Niklasson, G. (American Physical Society, 2003)
    We extend the Mayadas and Shatkes’s approach [Phys. Rev. B 1, 1382 (1970)] to study the optical properties of polycrystalline metal thick films in the visible and far infrared range of the spectrum. We show that in ...
