Publication number: 20190016904Abstract: 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.Type: ApplicationFiled: September 18, 2018Publication date: January 17, 2019Applicant: NanoCore TechnologiesInventors: Stephen T. Connor, James R. Groves, Theodore C. Sorom

Patent number: 9873938Abstract: 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.Type: GrantFiled: December 15, 2014Date of Patent: January 23, 2018Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Bruce M.

Patent number: 6899928Abstract: 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.Type: GrantFiled: July 29, 2002Date of Patent: May 31, 2005Assignee: The Regents of the University of CaliforniaInventors: James R.
