  • Swift, Paul; Solina, Danica; Cheary, Robert; Mccredie, Geoff (Elsevier Science Sa, 2003)
    Ultra-thin films are of interest in the production of X-ray mirrors that use a multilayer structure. The most commonly used deposition techniques are dc magnetron sputtering and electron beam evaporation; this paper presents ...
  • Rahmani, Adel; Steel, Michael; Chaumet, Patrick (American Physical Society, 2013)
    We study the radiation dynamics of an electric dipole source placed near or inside a discrete invisibility cloak. We show that the main features of radiation dynamics can be understood in terms of the interaction of the ...
  • Shanmukaraj, Devaraj; Wang, Guoxiu; Murugan, R.; Liu, Hua-Kun (Pergamon, 2008)
    The role of inorganic ceramic fillers namely nanosized Al2O3 (15?25 nm) and TiO2 (10?14 nm) and ferroelectric filler SrBi4Ti4O15 (SBT CIT) (0.5 ?m) synthesized by citrate gel technique (CIT) on the ionic conductivity and ...

    In this work, the flow of the Josephson vortices (JVs) has been studied for the highly anisotropic Bi2Sr2Ca2Cu3Oy (Bi2223) single crystals. A giant flow of JVs or giant positive magnetoresistance (MR) of over 500%-2000% ...
  • Steven, Randolph; Toth, Milos; Cullen, Jared; Chandler, Olive; Lobo, Charlene (American Institute of Physics, 2011)
    Electron beam induced etching (EBIE) is a high resolution, direct write, chemical dry etch process in which surface-adsorbed precursor molecules are activated by an electron beam. We show that nanoscale EBIE is rate limited ...
  • Wang, Xiu-Hong; Peleckis, G; Dou, Shi; Liu, Rong Mei; Zhu, Jianguo (Amer Inst Physics, 2007)
    We report on the magnetoresistance (MR) and magnetic properties of In1.90-xMn0.1SnxO3 (0 <= x <= 0.06) oxide. All samples were found to be ferromagnetic below T-C=46 K. Sn doping changed In1.90Mn0.1O3 from an insulator to ...
  • Xia, Hx; Guo, Wenshan; Wu, Xindong; Pi, Yong Lin; Bradford, Mark (Academic Press Ltd Elsevier Science Ltd, 2008)
    A dynamic model of a coupled train-girder-pier system is developed in this paper. Each vehicle in a train is modeled with 27 degrees-of-freedom for a 4-axle passenger coach or freight car, and 31 for a 6-axle locomotive. ...
  • Huang, Zaixing; Thomson, Peter; Di, Shenglin (Pergamon-Elsevier Science Ltd, 2007)
    The lattice parameters of a metallic nanoparticle decrease with its size. To describe this phenomenon, a model based on elasticity is developed in this paper. Using this model, we investigate the lattice contraction of a ...
  • Godlewski, Marek; Czernecki, R; Targowski, G; Perlin, Piotr; Leszczynski, M; Figge, Stephan; Hommel, Detlef; Phillips, Matt (Polish Academy of Sciences, 2005)
    Cathodoluminescence is applied for evaluation of in-depth and in-plane variations of light emission from two types of GaN-based laser diode structures. We evaluate in-depth properties of the laser diode emission and ...
  • Bosman, Michel; Keast, Vicki; Clarke, Jennifer; Cortie, Michael; Anstis, Geoff (Amer Chemical Soc, 2012)
    Nanoporous gold and silver exhibit strong, omnidirectional broad-band absorption in the far-field. Even though they consist entirely of gold or silver atoms, these materials appear black and dull, in great contrast with ...
  • Jonsson, Jacob; Roos, Arne; Smith, Geoff (International Society for Optical Engineering, 2003)
    When a beam of light is incident on a translucent sample, a significant fraction of the light is scattered at high angles. Some of this scattered light may be trapped inside the substrate through multiple reflections and ...
  • 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 ...
  • Kim, Icpyo; Nam, Tae-Hyun; Kim, Ki-Won; Ahn, Jou-Hyeon; Park, Dong-Soo; Ahn, Cheolwoo; Chun, Byong; Wang, Guoxiu; Ahn, Hyojun (Springer New York LLC, 2012)
    LiNi0.4Co0.3Mn0.3O2 thin film electrodes are fabricated from LiNi0.4Co0.3Mn0.3O2 raw powder at room temperature without pretreatments using aerosol deposition that is much faster and easier than conventional methods such ...
  • Ji, Zhengfeng; Feng, Yuan; Ying, Mingsheng (American Physical Soc, 2005)
    Local quantum operations and classical communication (LOCC) put considerable constraints on many quantum information processing tasks such as cloning and discrimination. Surprisingly, however, discrimination of any two ...
  • Asatryan, Ara; Botten, Lindsay; Fang, Kj; Fan, Sh; Mcphedran, Ross (Amer Physical Soc, 2013)
    We have constructed the Green's tensor for two-dimensional gyrotropic photonic clusters and have calculated their optical local density of states (LDOS). For clusters that support the chiral Hall edge states we calculate ...
  • Xin, Yu; Duan, Runyao (Amer Physical Soc, 2008)
    We present a complete characterization for the local distinguishability of orthogonal 2 circle times 3 pure states except for some special cases of three states. Interestingly, we find there is a large class of four or ...
  • 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. ...
  • Chaumet, Patrick; Rahmani, Adel; Nieto-Vesperinas, Manuel (Optical Society of America, 2006)
    We study the local-field enhancement in a nanocavity created by optical nanomanipulation. Recently we showed that a metallic probe can modify the optical force experienced by a metallic particle and generate a material ...
