摘要： Silicon-containing materials along with process for producing and uses for the same. The process includes reacting the silicon-containing materials in a fluidized bed reactor by deposition of silicon from at least one silicon precursor in pores and on the surface of porous particles. A fluidizing gas stream is provided within the fluidized bed reactor that is fully or partly induced to oscillate in a pulsed manner and propagates in the form of a wave and acts on the fluidized bed so as to form a homogeneously fluidized bed as a pulsed gas stream so as to form a homogeneously fluidized bed having a fluidization index FI of at least 0.95. Where the fluidizing gas stream has a superficial velocity which is above a measured minimum fluidization velocity of the pulsed gas stream and where the pulsation is combined with mechanical stirring as a further fluidizing aid.

摘要： Synthesis of silanes with more than three silicon atoms are disclosed (i.e., SinH(2n+2) with n=4-100). More particularly, the disclosed synthesis methods tune and optimize the isomer ratio by selection of process parameters such as temperature, residence time, and the relative amount of starting compounds, as well as selection of proper catalyst. The disclosed synthesis methods allow facile preparation of silanes containing more than three silicon atoms and particularly, the silanes containing preferably one major isomer. The pure isomers and isomer enriched mixtures are prepared by catalytic transformation of silane (SiH4), disilane (Si2H6), trisilane (Si3H8), and mixtures thereof.

摘要： Nano-wire growth processes, nano-wires, and articles having nano-wires are disclosed. The nano-wire growth process includes trapping growth-inducing particles on a substrate, positioning the substrate within a chamber, closing the chamber, applying a vacuum to the chamber, introducing a precursor gas to the chamber, and thermally decomposing the precursor gas. The thermally decomposing of the precursor gas grows nano-wires from the growth-inducing particles. The nano-wires and the articles having the nano-wires are produced by the nano-wire growth process.

摘要： Triphenylgermylsilane (Ph3Ge—SiH3) is useful for the production of germanium-silicon layers (Ge—Si) or as transfer agent of silane groups (SiH3). Further, a method describes the production of triphenylgermylsilane (Ph3Ge—SiH3) by reducing trichlorosilyl-triphenylgermane (Ph3Ge—SiCl3) with a hydride in solution, and another method describes the production of trichlorosilytrichlorogermane (Cl3Ge—SiCl3) by reacting trichlorosilyltriphenyigermane (Ph3Ge—SiCl3) with hydrogen chloride (HCl) in the presence of AlCl3 in solution. In addition, trichlorosilyltrichlorogermane is also used for the production of germanium-silicon layers (Ge—Si).

摘要： A polymerization inhibitor for a silane enables purification of the silane to a high degree because a polymer is not formed even when heating to distill the silane, even when a cyclic silane monomer is present. A high-purity cyclic silane composition is obtained, in particular high-purity cyclopentasilane, that can be polymerized and applied onto a substrate as a coating-type polysilane composition and fired to produce a good silicon thin film with high conductivity. The polymerization inhibitor includes a secondary or tertiary aromatic amine. The aromatic group is a phenyl group or a naphthyl group. The polymerization inhibitor is present in a proportion of 0.01 to 10 mol % per mole of the silane. In the polymerization inhibitor, a boiling point of the aromatic amine is 196° C. or higher.
