AbstractCo-reduction of mixtures of MoCl3(THF)3 and SiCls4 in THF using Li/C10H8 or both Li/C10Hs8 and LiBEt3H resulted in formation and separation of black powders which upon thermal annealing at temperatures ranging from 750°C to 1 100°C produced crystalline molybdenum silicide and silicon carbide composite. Co-reduction of mixtures of WCI4 and GeBr4 with LiBEt3H in THF formed W2C and elemental Ge which upon thermal treatment at 750°C for 4 hours generated a small amount of crystalline W5Ge3.

AbstractIn this study, we report a new wafer bonding technique for the integration of GaAs- and InP-based optical devices with prefabricated Si electronic devices in hybrid circuit technology. This technique uses a Au-Ge eutectic alloy as the bonding materials between GaAs and Si wafers, and between InP and Si wafers. This process takes advantage of the low temperature solid-state reactions at GaAs/Au-Ge, InP/Au-Ge, and Si/Au-Ge interfaces. The bonding was carried out by annealing the samples at 280–300°C in an alloying furnace. The reliability of the joined wafers was evaluated by both cleavage test and standard thermal cycling test. The joining interfaces were characterized by scanning electron microscopy and transmission electron microscopy. The results reveal that the bonding is achieved by low temperature reactions at the GaAs/Au-Ge and InP/Au-Ge interfaces as well as solid-phase epitaxial regrowth at the Si interfaces. The joined structure has very good integrity.

Abstract Single crystals of ra-Mg2CuV2O8 (I) and MgCu2V2O8 (II) have been prepared by solid state reactions. The orange (I) and dark red (II) crystals show monoclinic symmetry, space group C52h -P21/c, (I): a = 6.167(3), b = 8.172(5), c = 6.400(8) Å, β = 116.22(3)°, Z = 2; (II): a = 6.453(1), b = 8.342(2), c = 11.517(2)Å,β 90.44(2), Z = 4. Both compounds show ordered metal distributions and vanadium in tetrahedral coordination by oxygen. (I) is characterized by elongated CuO6 octahedra and (II) by trigonal CuO5 bipyramids. m-Mg2CuV2O8 is the low temperature form of the formerly investigated orthorhombic o-Mg2CuV2O8. Calculations of the Coulomb parts of the lattice energy of the two crystal forms are discussed
