  • Temperature dependence of optical and transport properties in VO2 with high temperature anomalies 
    Gentle Angus; Maaroof Abbas; Smith Geoffrey (Elsevier BV, 2008)
    Thermochromic VO2 is of interest for energy efficient glazing, and for fast telecommunications because it optically switches in the near IR. Despite extensive study several aspects of its apparently diverse behaviour have ...
  • Temporal Dynamics of the Alpha Factor in Semiconductor Optical Amplifiers 
    Poulton Christopher; Wang Jin; Maitra Ayan; Freude Wolfgang; Leuthold Juerg (IEEE Publications, 2007)
    The temporal evolution of the α-factor during pumpprobe experiments in semiconductor optical amplifiers (SOAs) is not constant but varies strongly with time. It even takes on negative values for short periods of time. ...
  • Thermal analysis of soft magnetic composite motors using a hybrid model with distributed heat sources 
    Guo Youguang; Zhu Jianguo; Wu Wei (Institute of Electrical and Electronics Engineers, 2005)
    This paper presents a hybrid thermal model with distributed heat sources for thermal analysis of soft magnetic composite (SMC) motors. The model uses a combination of lumped and distributed thermal parameters, which can ...
  • Thermal And Spontaneous Remagnetization In Ferromagnetic Nd3(FeTi)(29) And Nd3(FeRe)(29) 
    Collocott Stephen; Dunlop John; Watterson Peter (American Physical Society, 2007)
    Magnetization measurements at 10 K on the dc demagnetized ferromagnetic intermetallic compounds Nd3(Fe,Ti)29 and Nd3(Fe,Re)29 are reported and reveal the phenomena of thermal and spontaneous remagnetization. For both ...
  • Thin films of ZnO and ZnMnO by atomic layer epitaxy 
    Wojcik Aleksandra; Kopalko Krzysztof; Godlewski Marek; Lusakowska Elzbieta; Guziewicz Elzbieta; Minikayev Roman; Paszkowicz Wojciech; Swiatek Krzysztof; Klepka Marcin; Jakiela Rafal; Kiecana Michel; Sawicki Maciej; Dybko Krzysztof; Phillips Matthew (Institute of Physics, Wroclaw University of Technology and SPIE - The International Society for Opti, 2005)
    We discuss properties of thin films of ZnO and ZnMnO grown with atomic layer epitaxy using new, organic zinc and manganese precursors. Several characterization techniques, including X-ray diffraction, atomic force microscopy, ...
  • Third harmonics due to surface barrier in high-temperature superconductor 
    Xu X; Zhang L; Leng X; Ding S; Liu Hua Kun; Wang Xiu-Hong; Dou Shi; Lin Zhi Wei (Jack); Zhu Jianguo (American Institute of Physics, 2005)
    The influence of surface barrier on the third harmonics ac susceptibility sx3d is studied numerically. The surface barrier is described by a critical current density in surfaces which are higher than the inside one. The ...
  • Three-dimensional hysteresis of soft magnetic composite 
    Lin Zhi Wei (Jack); Zhu Jianguo; Guo Youguang; Wang Xiu-Hong; Ding S (American Institute of Physics, 2006)
    Hysteresis phenomenon is one of the important characteristics of soft magnetic materials. A three-dimensional (3D) magnetic property measurement system has been developed. This system can effectively control the locus ...
  • Trends in the band structures of the group-I and -II oxides 
    Mikajlo Elisabeth; Dorsett Helen; Ford Michael (American Institute of Physics, 2004)
    Measured and calculated band structures for the six lightest Group I and II oxides are reported. Band structures have been measured using electron momentum spectroscopy, a technique that maps the ground state occupied ...
  • Tuning the surface-plasmon resonance in nanoparticles for glazing applications 
    Schelm Stefan; Smith Geoffrey; Garrett Paul; Fisher W (American Institute of Physics, 2005)
    Issues affecting the performance of polymers doped with conducting nanoparticles for use with windows are examined in terms of impact on visible and solar transmittance, solar heat gain, and residual scattering. Emphasis ...
  • Uniform MgB2 thin films grown on Si(111) and Al2O3(0001) substrates prepared by e-beam evaporation and in situ annealing methods 
    Zhang Y; Zhu H; Zhou Sihai; Ding S; Lin Zhi Wei (Jack); Zhu Jianguo (American Institute of Physics, 2006)
    MgB2 superconducting thin films on Si(111) and Al2O3(0001) substrates were prepared by high vacuum e-beam evaporation and two-step in situ annealing techniques. The precursor films [B(100 Å)/Mg(151 Å)]6/Al2O3 (or Si) ...
  • Vector characterization of soft magnetic materials 
    Lin Zhi Wei (Jack); Lu Haiwei; Zhu Jianguo; Zhong Jin Jiang; Wang Xiu-Hong; Ding S (American Institute of Physics, 2005)
    A three-dimensional (3D) magnetic property testing system has been completed and successfully used to measure 3D hysteresis loci of soft magnetic material. This paper presents the techniques to characterize soft magnetic ...
  • Why do Bell Plates Ring? 
    Lavan Daniel; Hogg Suzanne; Wolfe Joe (Australian Acoustical Society, 2003)
    Bell plates are polygonal plates which, when held in the hand and struck with a beater, produce an initial transient followed by a sustained, pure tone. The presence of the sustained tone depends sensitively on the shape. ...
  • X-ray mapping and post processing 
    Wuhrer Richard; Moran Ken; Phillips Matthew (Cambridge University Press, 2006)
  • X-ray mapping using a multiple-EDS (DUAL) detector 
    Wuhrer Richard; Moran Ken; Phillips Matthew; Davey P (Cambridge University Press, 2006)
  • X-ray spectrometry investigation of electrical isolation in GaN 
    Kucheyev Sergei; Toth Milos; Phillips Matthew; Williams Jim; Jagadish Chennupati; Li Gang (American Institute of Physics, 2002)
    Electrical isolation of n-type GaN epilayers bombarded with MeV light ions is studied by energy dispersive x-ray spectrometry (EDS). We show that the maximum bremsstrahlung x-ray energy (the Duane–Hunt limit) can be used ...
