    Effects of external electric field upon the photonic band structure in synthetic opal infiltrated with liquid crystal (2001)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 89 (2001), S. 5794-5796

    Notes: Based on the electrically controlled birefringence effects of a nematic liquid crystal, a tunable photonic band gap crystal has been fabricated by infiltrating nematic liquid crystal into the voids of synthetic opal composed of silica spheres. A reversible shift of the photonic band gap position and a change of transmittance through the composite opal can be induced by applying an external electric field. © 2001 American Institute of Physics.

    Spectroscopic Kerr investigations of CoNi/Pt multilayers : The 40th annual conference on magnetism and magnetic materials (1996)
    [S.l.] : American Institute of Physics (AIP)

    Notes: CoxNi1−x/Pt multilayers with x=0.4 and 0.5 were sputtered onto Si substrates. Magnetic and spectroscopic magneto-optic measurements (1.4–5.2 eV) reveal a Kerr rotation up to −0.48° at about 4.5 eV for a sample with rectangular hysteresis loop, about 170 kA/m coercivity, and a Curie temperature of about 300 °C. Pt layers could be made extremely thin (2.9 A(ring)) without loss of perpendicular anisotropy and rectangular hysteresis loop. Simulations show that the Kerr rotation peak shifts back from 4.5 to 3.9 eV with increasing number of bilayers. © 1996 American Institute of Physics.

    Self-assembly of submicron particles between electrodes (2001)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 90 (2001), S. 2042-2044 
    Details
    ISSN: 1089-7550

    Topics: Physics
    Notes: A method for the fabrication of opal films between parallel transparent electrodes is described. Monodispersed particles are assembled by taking advantage of the rheological force induced by the evaporation of a solvent in a thin capillary cell. Three-dimensional opal films with controllable thickness could be fabricated, in which a regular hexagonal arrangement of particles parallel to the substrates over a large area was observed. Such a sandwich-like photonic device may find applications in fabricating electrically tunable photonic crystals. © 2001 American Institute of Physics.

    Fabrication of highly ordered porous structures (2000)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 77 (2000), S. 4313-4315 
    Details
    ISSN: 1077-3118
    Source: AIP Digital Archive
    Topics: Physics
    Notes: We describe a simple method for the fabrication of highly ordered porous structures. That is, utilizing capillary forces, ultrafine particles are directly used to assemble themselves in the voids of template while the template is being assembled. The highly ordered porous structures with larger area and uniform orientation can be produced after removing the template. The majority of the single domains with uniform orientation prepared can reach 0.1 mm2 in area. Scanning electron microscope images and transmission spectrum of these samples have confirmed the success of this simple method. © 2000 American Institute of Physics.

    Preliminary study on the charge transfer and bond ionicity of binary crystals (1998)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: Charge transfer and bond ionicity of some monovalent, divalent, and trivalent binary crystals of ANB8−N type have been investigated using the self-consistent method. The method divides the binary crystal systems into two subsystems which contain only one kind of element each in physical space. The charge transfer values are obtained by adjusting the charge in a self-consistent way. Based on the obtained charge transfer values, an empirical formula for bond ionicity has been proposed. It has been shown that the present results for bond ionicity are in good agreement with the previous theoretical study delivered by Levine and Pauling. The results also indicate that a large magnitude of charge transfer (or less excess charge in the bonding region) gives rise to high bond ionicity (or low bond covalency); this agrees well with the viewpoint that the excess charge in the bonding region is the origin of the formation of bond covalency. © 1998 American Institute of Physics.
