  • Hodgkinson, Ian; Wu, Qi; Arnold, Matthew; Blaikie, Richard (Elsevier, 2001)
    Biaxial and chiral thin films formed by oblique vapour deposition are patterned using standard photolithography. In one example 5 ?m wide half-wave plates are fabricated by reactive ion etching a biaxial silicon film.
  • Marshall, Graham; Ams, Martin; Little, Doug; Jovanovic, Nemanja; Fuerbach, Alex; Dekker, Peter; Rahmani, Adel; Dawes, Judith; Piper, Jim; Withford, Michael (IEEE, 2007)
    Ultrafast laser direct write micro-fabrication has emerged as a significant enabling technology creating new opportunities in microphotonics. The talk will present recent results of the performance of laser written ...
  • Gentle, Angus; Smith, Geoff; Watkins, Se (Elsevier Science Bv, 2013)
    A novel photoemission technique utilising localised discharge amplification of photo-yield is reported. It enables fast, accurate measurement of work function and ionisation potential for ultra-thin buffer layers vacuum ...
  • Rahmani, Adel; Chaumet, Patrick; Bryant, Garnett (Optical Society of America, 2010)
    We develop a general computational approach, based on the discrete dipole approximation, for the study of radiation dynamics near or inside an object with arbitrary linear dielectric permittivity, and magnetic permeability ...
  • Rahmani Adel; Chaumet Patrick; Bryant Garnett (Optical Society of America, 2010)
    We develop a general computational approach, based on the discrete dipole approximation, for the study of radiation dynamics near Of inside an object with arbitrary linear dielectric pennittivity, and magnetic penneability ...
  • Chaumet, Patrick; Belkebir, Kamal; Rahmani, Adel (Optical Soc Amer, 2011)
    We present a general approach, based on the discrete dipole approximation (DDA), for the computation of the exchange of momentum between light and a magnetodielectric, three-dimensional object with arbitrary geometry ...
  • Zhang, Chi; Wang, Guoming; Ying, Mingsheng (American Physical Soc, 2007)
    In this paper, we discuss the problem of determining whether a quantum system is in a pure state, or in a mixed state. We apply two strategies to settle this problem: the unambiguous discrimination and the maximum confidence ...
  • Cheng, Eric; Piccardi, Massimo (SPIE-Int Society Optical Engineering, 2007)
    A disjoint track matching algorithm is proposed based on major color spectrum histogram representation (MCSHR) matching and post-matching integration algorithms; this algorithm is useful for reconnecting broken tracks due ...
  • Gelhausen, Olaf; Goldys, Ewa; Paskova, Tanja; Monemar, Bo; Strassburg, M; Hoffmann, Axel; Phillips, Matt (American Physical Soc, 2004)
    Post-growth annealing and electron beam irradiation during cathodoluminescence were used to determine the chemical origin of the main optical emission lines in moderately and heavily Mg-doped GaN. The 3.27 eV donor-acceptor ...
  • Duan, Runyao; Feng, Yuan; Xin, Yu; Ying, Mingsheng (IEEE-Inst Electrical Electronics Engineers Inc, 2009)
    In this paper, we study the distinguishability of multipartite quantum states by separable operations. We first present a necessary and sufficient condition for a finite set of orthogonal quantum states to be distinguishable ...
  • Gelhausen, Olaf; Malguth, Enno; Goldys, Ewa; Strassburg, M; Hoffmann, Axel; Graf, T; Gjukic, M; Stutzmann, M; Phillips, Matt (American Institute of Physcis, 2004)
    The optical properties of molecular-beam-epitaxy-grown GaN with different Mn-doping levels (5?23?1019 cm?3) were studied by cathodoluminescence (CL) and optical transmission spectroscopy. Transmission measurements at 2 K ...
  • Weston, Leigh; Ton-That, Cuong; Phillips, Matt (Materials Research Society, 2012)
    The doping properties and stability of hydrogen in zinc oxide (ZnO) crystals have been investigated by cathodoluminescence (CL) spectroscopy. Hydrogen incorporation was achieved by hydrogen plasma at 200 ?C. The ZnO ...
  • Pi, Yong Lin; Bradford, Mark (Academic Press Ltd Elsevier Science Ltd, 2008)
    When a shallow arch is subjected to an in-plane load that is applied suddenly, the arch will oscillate about an equilibrium position due to the kinetic energy imparted to the arch by the sudden load. If the suddenly applied ...
  • Clowes, Shaun; Cohen, Graeme; Tomljanovic, Ljiljana (UTS, 2002)
  • Crowther, Ashley; Zhang, Nong (Australian Acoustical Society, 2004)
    Torsional finite elements for direct, geared, branched and grounded connections are presented. For a simple three-degrees-of-freedom powertrain model the finite elements are defined and the global system assembly is detailed. ...
  • Zhang, Nong; Kirpitchenko, Inessa; Liu, Dikai (Academic Press Ltd Elsevier Science Ltd, 2005)
    Grinding is one of the most versatile methods of removing material from machine parts to provide precise geometry. Dynamic analysis of the grinding process is necessary to reduce the surface waviness and roughness induced ...
  • Godlewski, Marek; Yatsunenko, S; Drozdowicz-Tomsia, Krystyna; Goldys, Ewa; Klar, Peter; Heimbrodt, Wolfram; Phillips, Matt (Polish Academy of Sciences, 2005)
    We demonstrate coexistence of slow and fast components of photoluminescence decay of the Mn?^(+) intra-shell emission in nanoparticles of CdMnS. We explain the observed decrease in PL lifetime of the Mn?^(+) intra-shell ...
