    Electrical and Optical Studies of the Organic Thin Film Devices Produced by Cluster Beam Deposition Methods

    The neutral and ionized cluster beam deposition (NCBD and ICBD) methods have been applied to fabricate the new double-layer organic light emitting devices (OLEDs) with the structure of indium-tin-oxide (ITO)-c...

    Effect of Cu content on the mechanical reliability of Ni/Sn-3.5Ag system

    Copper was supplied to Sn–3.5Ag by electroplating Cu/Ni double under-bump metallization (UBM), and the amount of Cu was controlled by varying the Cu UBM thickness. Supposed Cu contents in the solder were; 0.2,...

    High-temperature tolerance of the silver-copper oxide braze in reducing and oxidizing atmospheres

    The silver-copper oxide–based reactive air brazing technique was developed as a method of joining complex-shaped ceramic parts. To investigate the viability of this approach for high-temperature application, a...

    Silver-copper oxide based reactive air braze for joining yttria-stabilized zirconia

    We investigated a new method of ceramic-to-metal joining, referred to as reactive air brazing, as a potential method of sealing ceramic components in high-temperature electrochemical devices. Sessile drop wett...

    An approach to durable poly(vinylidene fluoride) thin film loudspeaker

    The piezoelectric poly(vinylidene fluoride) (PVDF) surface possessing low surface energy was modified by the ion-assisted-reaction (IAR) method for the application of thin film speaker. The IAR-treated hydroph...

    Measurements of the Hydrogen Absorption Pressurecomposition Isotherms IN Ti/Zr-Based Quasicrystals

    The first hydrogen absorption pressure-composition isotherms (p-c-T) were measured in quasicrystalline Ti45Zr38Ni17. No evidence for a pressure plateau was found, indicating a distribution of energies for the hyd...

    Hydrogen Sites in the α(TiCrSiO) 1/1 Approximant Phase

    Crystal approximant phases are important because they are believed to have a similar local atomic structure to corresponding quasicrystals. Interstitial hydrogen is used as a probe of the local structures of t...

    Exafs Evidence For Atom Location in Icosahedral TiZrNi and Hydrogenated TiZrNi Quasicrystals

    We present results from the first extended X-ray absorption fine-structure studies in a Ti/Zrbased quasicrystal. the icosahedral Ti53Zr27Ni20 phase and an icosahedral Ti45Zr38Ni17 phase that also contains 1.7 hyd...
