  • Publication number: 20190016904
    Abstract: A material and method are disclosed such that the material can be used to form functional metal pieces by producing an easily sintered layered body of dried metal paste. On a microstructural level, when dried, the metal paste creates a matrix of porous metal scaffold particles with infiltrant metal particles, which are positioned interstitially in the porous scaffold's interstitial voids. For this material to realize mechanical and processing benefits, the infiltrant particles are chosen such that they pack in the porous scaffold piece in a manner which does not significantly degrade the packing of the scaffold particles and so that they can also infiltrate the porous scaffold on heating. The method of using this paste provides a technique with high rate and resolution of metal part production due to a hybrid deposition/removal process.

  • Patent number: 9873938
    Abstract: A biaxially textured crystalline layer formed on a substrate using ion beam assisted deposition (IBAD) is provided. The biaxially textured crystalline layer includes an oriented CaF2 crystalline layer having crystalline grains oriented in both in-plane and out-of-plane directions, where the out-of-plane orientation is a (111) out-of-plane orientation. The oriented CaF2 crystalline layer is disposed for growth of a subsequent epitaxial layer and the CaF2 crystalline layer is an IBAD CaF2 layer. The biaxially textured CaF2 layer can be used in a photovoltaic cell, an electronic or optoelectronic device, an integrated circuit, an optical sensor, or a magnetic device.

  • Publication number: 20100009176
    Abstract: An article including a substrate, a layer of an inert oxide material upon the surface of the substrate, (generally the inert oxide material layer has a smooth surface, i.e., a RMS roughness of less than about 2 nm), a layer of an amorphous oxide or oxynitride material upon the inert oxide material layer, a layer of an oriented cubic oxide material having a rock-salt-like structure upon the amorphous oxide material layer is provided together with additional layers such as at least one layer of a buffer material upon the oriented cubic oxide material layer or a HTS top-layer of YBCO directly upon the oriented cubic oxide material layer. With a HTS top-layer of YBCO upon at least one layer of a buffer material in such an article, Jc's of 1.4×106 A/cm2 have been demonstrated with projected Ic's of 210 Amperes across a sample 1 cm wide.

  • Patent number: 6899928
    Abstract: The present invention is directed towards a process and apparatus for epitaxial deposition of a material, e.g., a layer of MgO, onto a substrate such as a flexible metal substrate, using dual ion beams for the ion beam assisted deposition whereby thick layers can be deposited without degradation of the desired properties by the material. The ability to deposit thicker layers without loss of properties provides a significantly broader deposition window for the process.
