  1. Implications of Crystal Structure on Organotin Carboxylate Photoresists

    Meredith C. Sharps, David A. Marsh, Lev N. Zakharov, James E. Hutchison and Darren W. Johnson

    A series of five organotin carboxylate clusters of the type [RSn(O)O2CR’]6 have been synthesized and examined by single crystal X-ray diffraction. The crystal structures have been compared with regards to the steric and intermolecular forces dictated by the ligand groups as a means to understand how these same factors affect irradiation trends in lithography of thin films. Trends found are compared to other factors that may also dictate resist formation.

  2. One-Step Formation of 3D Alternating-Layer Structures Composed of Plates of Nanocrystalline Bismuth Oxide and Spherical Particles of Metallic Bismuth

    The authors demonstrate a possibility of synthesizing a periodic heterostructure consisting of layers of nanocrystalline β-bismuth oxide and layers of spherical particles of metallic bismuth in a single step by conducting partial reduction of [Bi6O5(OH)3](NO3)5·3H2O in benzyl alcohol. The mechanisms governing the interface formation during the synthesis of the β-Bi2O3/spherical Bi alternating-layer structure are discussed.

  3. Structural Infrared Analysis of Ultra Nanosized Crystals of Yttria-Stabilized Zirconia

    The tetragonal and cubic phases of yttria-stabilized zirconia ultra nanosized crystals are distinguished using infrared spectroscopy. Based on the infrared spectra, the percentage of crystal phases can be calculated. The results shows that the grain size of the cubic phase decreases from 11.7 to 5.2 nm with increasing yttrium content. Furthermore the nanocrystal effect also results in wider peaks in the infrared spectra.

  4. High-Quality GaSb and GaInSb Crystals Prepared by Vertical Bridgman Method

    Jinwei Wang, Liguo Wang, Dongxiao Teng, Shenqiu Zhai and Juncheng Liu

    High-quality GaSb and Ga1-xInxSb (x = 0.14) crystals were grown via the vertical Bridgman method. The results demonstrate that the segregation of indium is very low, with the radial and axial concentration variation of 2.32% and 4.84%, respectively. The indium doping significantly reduces the dislocation density down to 1.275 × 103 cm−2. The GaInSb crystal shows enhanced transport properties, with carrier mobility increased to 2.512 × 103 cm2/(V•s) and resistivity reduced to 0.521 × 10−3 ohm•cm.

  5. Mechanical Characterization of EuD4TEA- and ZnS:Mn-Enhanced Composites

    The authors assess triboluminescent (TL) materials as components in structural health monitoring (SHM) systems within polymer composites. Processing must be addressed due to particle characteristics such as density, morphology, and chemical makeup, all of which can affect polymer curing dynamics and thermo-mechanical properties. The authors consider key processing parameters during incorporation of TL compounds into various polymers and develop a model to predict composite modulus.
