    Notes: Several etchants have been applied to polar (111)Cd and (111)Te surfaces of CdTe. Induced surface layers were analyzed by x-ray photoelectron spectroscopy and grazing-incidence x-ray diffraction for studying compositions, chemical states, and crystalline phases of respective layers. A bromine/methanol etch led to a layer composed of mainly tellurium oxides on both (111) surfaces. Oxidation depth, however, was larger at the (111)Te side. Etching with HCl subsequently removed the oxides. A film made of crystalline tellurium was, however, produced with the thickness being larger on the (111)Te surface than on the other surface. A fairly thick layer consisting of TeO2 and crystalline Te for etching with N solution (H2O2:H2O:HF=2:2:3 v/v), formed on both surfaces with the cadmium having been severely depleted, especially on the (111)Te surface.

    Notes: We have measured the femtosecond dynamics of the nonlinear optical response χ(3) in polydiethynylsilane (C4H2SiBu2)x, a novel class of π-conjugated polymers incorporating Si, using degenerate four-wave mixing and photoinduced absorption techniques. In resonance conditions at 620 nm we found χ(3)=3×10−9 esu, which decays in a record time of 135 fs, followed by a slower decay component of 750 fs, without a long tail even at high laser intensities. This material is an excellent candidate for nonlinear optical devices in the sub-THz frequency range.

    Hydrogen passivation in Cd1−xZnxTe studied by photoluminescence (1991)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: It is shown for the first time that deep defects in single-crystal CdZnTe can be passivated by atomic hydrogen. This treatment can result in a strong enhancement in the photoluminescence intensity of all excitonic transitions. In addition, it is shown that after hydrogenation, the higher-order emission of free exciton in CdZnTe alloys is observed for the first time; the mixed bands can be separated; the LO phonon energy, the binding energy of free exciton, and the concentration of Zn content are also determined. From the experimental results it is inferred that hydrogenation not only improves the sample quality but also provides an excellent opportunity to probe the physical properties of a material.

    Exchange coupling of ferromagnetic films across nonmagnetic interlayers (1987)
    [S.l.] : American Institute of Physics (AIP)

    Notes: We have studied exchange coupling between ferromagnetic films across nonmagnetic intermediate layers by means of light scattering from spin waves and microwave absorption. The ferromagnetic films were Ni0.8Fe0.2 (permalloy) and Fe and we chose Au, Ag, Cu, V, Cr, Pd, Ge, Si, Mn, and Bi as nonmagnetic interlayer materials. As expected the effective interlayer exchange decreases when the interlayer thickness d0 increases. Minimum thickness d0 where the ferromagnetic films are exchange decoupled range between 10 and 40 A(ring). We compare these results with the concentration dependence of the magnetic ordering temperature in alloys of Fe and Ni with other elements, taking this as a measure for the strength of the exchange. There is a good correspondence which indicates that the coupling effects in the layered structures and the alloys have the same origin which is presumably by RKKY interaction.

    Layered magnetic structures: Evidence for antiferromagnetic coupling of Fe layers across Cr interlayers (1987)

    Notes: Double layers of (100)-oriented Fe with an individual thickness of ≈100 A(ring), separated by interlayers of Cr or Au with variable thickness were grown epitaxially on Au (100) surfaces. The spin-wave mode spectra of these double layers as detected by means of light scattering were used to measure the effective exchange coupling of the Fe films across the interlayer. For Au interlayers it decreases monotonically with increasing Au thickness dAu and disappears at dAu(approximately-greater-than)20 A(ring). For Cr interlayers of proper thickness dCr, i.e., 4 A(ring)(approximately-less-than)dCr(approximately-less-than)9 A(ring) we obtain antiferromagnetic coupling of the Fe layers. In small external fields such double layers order antiparallel with their magnetization perpendicular to the external field in analogy to the spin-flop phase of antiferromagnets. This is revealed by the behavior of the static magnetization of such samples as a function of external field and the spectrum of spin-wave modes with the wave vector parallel to a small external field.

    Preparation of Hg1−xCdxTe with a semiclosed rotational liquid-phase-epitaxy system (1987)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Hg1−xCdxTe epitaxial layers were grown on CdTe substrates by the liquid-phase-epitaxy method in a horizontal open system. A semiclosed rotational boat was developed to prevent Hg loss from the Te-rich growth melt during growth processes. The solid composition of HgTe-rich Hg1−xCdxTe layers can be reproducibly controlled. Through the rotation mechanism, the melt entrapment on the as-grown surface can be avoided. With a small amount of excess Hg added into the growth melt and in situ annealing at 300 °C right after the growth, an n-type epilayer can be obtained. The electron concentration of 3×1015 cm−3 and the electron mobility of 7.5×104 cm2/V s were obtained.

    A new lattice formulation of the continuum (1994)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: A new lattice formulation of the continuum is presented, which can be applied to quantum or classical field theories in any space–time dimension. The method is illustrated with an application to relativistic nontopological solitons. This approach also provides an effective means of removing the spurious lattice fermion degenerate solutions for the Dirac equation.

    Homozygous transgenic rice lines expressing GNA with enhanced resistance to the rice sap-sucking pest Laodelphax striatellus (2002)

    Notes: Homozygous transgenic rice lines expressing snowdrop lectin, Galanthus nivalis agglutinin (GNA), were investigated for resistance to the rice small brown planthopper (SBPH), Laodelphax striatellus, an important rice sap-sucking pest causing yield losses and serving as vector for some important rice viruses. Insect bioassay results revealed that both the GNA-expressing homozygous lines tested significantly inhibited SBPH by decreasing its survival, its overall fecundity and retarding development. This is the first report on homozygous transgenic rice lines expressing GNA conferring enhanced resistance to SBPH. This result suggests that transgenic rice expressing GNA will be useful in rice pest resistance breeding, as an alternative to conventional breeding for the control of SBPH, and potentially alleviating damage caused by the viruses it transmits.

    MODELING RELATIVISTIC HEAVY ION COLLISIONS AT THE AGS1 (1996)

    Notes: Abstract A quantitative model, based on hadronic physics and Monte Carlo cascading, is described and applied to heavy ion collisions at BNL-AGS energies (~ 14 GeV/u). The model was found to be in excellent agreement with particle spectra where data previously existed, for Si beams, and was able to successfully predict the spectra where data were initially absent, for Au beams. For Si + Au collisions, baryon densities of three or four times the normal nuclear matter density (rho0) are seen in the theory, whereas for Au + Au collisions, matter at densities up to 10 rho0 is anticipated. The possibility that unusual states of matter may be created by the Au beams and potential signatures for its observation are considered.
