  • Patent number: 10043964
    Abstract: A pyroelectric device having a substrate and a first electrode overlying at least a portion of the substrate. A plurality of spaced apart nanometer sized pyroelectric elements are electrically connected to and extending outwardly from the first electrode so that each element forms a single domain. A dielectric material is deposited in the space between the individual elements and a second electrode spaced apart from said first electrode is electrically connected to said pyroelectric elements.
    Type: Grant
    Filed: May 26, 2017
    Date of Patent: August 7, 2018
    Assignee: The United States of America as represented by the Secretary of the Army

  • Publication number: 20180112331
    Abstract: Integrated non-linear complex oxide (NLCO) thin film artificial structures include tailored microstructural and crystalline phases for designed material architectures and a method of fabrication. A nano-scale poly crystal-amorphous composite film includes an amorphous matrix surrounding crystalline domains/inclusions of the form of particles, platelets, rods and/or needles, etc. Artificial thin film layered material configurations include bilayers, repeat “unit cell” bilayers with variable stacking periodicity (N), and multilayers whereby each individual layer, ni, exhibits a different microstructural crystallinity phase state, hence the microstructural phase state is variable in the vertical direction perpendicular to the substrate. NLCO elements can be organized in array configurations.

  • Patent number: 9666729
    Abstract: An electronic device in the form a two-dimensional array of nanopillars extending generally normal to a substrate is provided. The nanopillars are made from a paraelectric or superparaelectric material. In addition, a linear dielectric medium is located between individual nanopillars. A two-dimensional array of paraelectric or superparaelectric nanopillars and a linear dielectric medium form the effective dielectric medium of a paraelectric or superparaelectric varactor. In some instances, the nanopillars are cylindrical nanopillars that have an average diameter and/or average height/length between 1-300 nanometers. In other instances, the nanopillars are quasi-nanoparticles that form self-aligned nano-junctions. In addition, each of the nanopillars has a single paraelectric or superparaelectric dipole domain therewithin. As such, each of the nanopillars can be void of crystallographic defects, polycrystallinity, interactions between ferroic domains, and defects due to ferroic domain walls.
