    The optical reflectivity of a GaAs wafer is found to decrease from about 45% down to about 5% for both the g-line and i-line by oxidation in low-power oxygen plasma at 300-degrees-C for 4 hours. The oxide layer on the GaAs top surface used as an in situ antireflection layer for optical microlithography is demonstrated to be effective.

    Highly c-axis-oriented Tl2Ba2Ca2Cu3O(x) superconducting thin films with the critical current density as high as 1 X 10(7) A/cm2 at 87 K were obtained by single-target dc sputtering on LaAlO3 (100) substrates followed by encapsulated compensate annealing. The strong linear temperature dependence of zero-field critical current at low temperatures suggests a creep-dominated behavior. Preliminary field dependence studies on the critical current density in low-field regime (< 2 kOe) shows no evidence of hysteresis commonly encountered in films with higher granularity. The scaling behavior of the global pinning force density exhibits strong resemblance to conventional type-II superconductors with the pinning force density of the same order of magnitude as that in strong pinned NbN thin films.

    The current-voltage characteristics (IVC) of Tl-based superconducting thin films as well as the magnetization of the Tl-based bulk sample were investigated. A crossover similar to the prediction of the vortex-glass to vortex-liquid phase transition in the IVC of Tl-based superconducting thin films was clearly demonstrated. More significantly, striking scaling behavior was found in the IVC which is only sample dependent and is irrelevant to the applied magnetic fields. By comparison to dc magnetization measurements on similar bulk samples, it is found that the phase boundary is not the irreversibility line commonly encountered in the flux-creep scenario.

    The synthesis of four side-chain liquid crystalline polymethacrylates containing either 4-alkanyloxy-4'-flourodiphenyldiactylenes or 4-alkanyloxy-3',4'-difluorodiphenyldiacetylenes side groups is presented. The phase behavior of both monomeric and polymeric liquid crystals was characterized by differential scanning calorimetry and optical polarizing microscopy. All synthesized polymethacrylates present nematic mesomorphism. The glass transition temperature of the obtained polymers decreases as the spacer length increases. The mesomorphic behavior of the prepared polymers depends very much on the degree of substitution of the mesogenic side groups on the polymer backbones.

    The addition of ZrO2 is found to be very effective as the nucleation sites to promote the oriented growth of Y1Ba2Cu3O7-delta (YBCO) during peritectic solidification. Extended regions of well-textured YBCO grains with superior superconducting properties of the YBCO bulk are readily obtained by a single-step melt process at much lower process temperatures. At 77 K, the platelike Josephson weak-link behaviors observed in pure melt-processed YBCO have been effectively eliminated, indicating that the coherency between the spherulitic superconducting YBCO grains may have been greatly improved by ZrO2 additions.

    The synthesis and characterization of side-chain liquid crystalline polyoxetanes containing 4-dodecanyloxyphenyl trans-4-alkylcyclohexanoate side groups are presented. All the obtained monomers exhibit smectic B mesomorphism, while all the obtained polymers present smectic A, smectic B and smectic G mesophases. A longer terminal alkyl group is leading to the formation of a more stable mesophase.
