  • Patent number: 10556822
    Abstract: Certain example embodiments relate to a coated article including at least one infrared (IR) reflecting layer of a material such as silver or the like in a low-E coating, and methods of making the same. In certain cases, at least one layer of the coating is of or includes nickel and/or titanium (e.g., NixTiyOz). The provision of a layer including nickel titanium and/or an oxide thereof may permit a layer to be used that has good adhesion to the IR reflecting layer, and reduced absorption of visible light (resulting in a coated article with a higher visible transmission). When a layer including nickel titanium oxide is provided directly over and/or under the IR reflecting layer (e.g., as a barrier layer), this may result in improved chemical and mechanical durability. Thus, visible transmission may be improved if desired, without compromising durability; or, durability may simply be increased.

  • Patent number: 10543516
    Abstract: Liquid-impregnated textured coatings containing one or more materials on a variety of surfaces are described herein. The coatings can be prepared by chemical vapor deposition techniques or other techniques known in the art. The texture can be random, fractal, or patterned. The texture can be pores, cavities, and/or micro- and/or nanoscale features/structures.

  • Patent number: 10538844
    Abstract: Methods and systems for direct lithographic pattern definition based upon electron beam induced alteration of the surface chemistry of a substrate are described. The methods involve an initial chemical treatment for global definition of a specified surface chemistry (SC). Electron beam induced surface reactions between a gaseous precursor and the surface are then used to locally alter the SC. High resolution patterning of stable, specified surface chemistries upon a substrate can thus be achieved. The defined patterns can then be utilized for selective material deposition via methods which exploit the specificity of certain SC combinations or by differences in surface energy. It is possible to perform all steps in-situ without breaking vacuum.

  • Patent number: 10526694
    Abstract: A method of preparing an ultra-flat metal surface involves providing a layer of a crystalline metallic material on an ultra-flat substrate surface that is relatively harder than the metallic material layer and then impinging the metallic material layer with incoming metal atoms that are deposited as an additive crystalline layer thereon, wherein at least a lattice constant of the additive crystalline layer is different enough from a lattice constant of the crystalline metallic material layer resulting in a reduction of roughness of the surface of the metallic material layer adjacent to the substrate surface. The metallic material layer having an ultra-flat surface then is separated by template stripping or other technique from the substrate surface for further use of the ultra-flat surface.
