    Abstract: A single step method of forming a composite of ductile niobium particles within a matrix of brittle niobium aluminum is taught. The method involves completely ablating the end of a rod of a niobium aluminum intermetallic with a laser beam to form a plume of vaporous and particulate material and depositing the ablated material on a receiving surface disposed proximate the rod end being ablated. A surface composite structure is formed in a single step and has ductile particles within a brittle matrix.

    Abstract: A semiconductor material structure includes at least one region capable of generating electrons and holes each having an associated mean kinetic energy during operation. A material layer in proximity to the region provides an associated potential energy larger than the mean kinetic energy associated with the generated electrons and the mean kinetic energy associated with the holes.

    Abstract: Doped tungsten powder, or sintered tungsten bodies formed therefrom, having a fine dispersion of oxide particles of at least one metal from the group zirconium, hafnium, lanthanum, yttrium, and rare earth's are formed by the method of this invention. A mixture of a salt solution comprised of a soluble salt of the metal, and a tungsten blue oxide powder is formed. A hydroxide precipitating solution is admixed with the mixture to form a hydroxide precipitate of the metal on the tungsten blue oxide powder. The tungsten blue oxide powder and hydroxide precipitate are heated in a reducing atmosphere to form the tungsten powder having the dispersion of oxide particles. The doped tungsten powder can be consolidated and sintered to form tungsten bodies having a fine dispersion of the metal oxide.
