  • Patent number: 9890480
    Abstract: Poly-(caffeyl alcohol) (PCFA), also known as C-lignin, is a promising new source of both carbon fibers and pure carbon. PCFA can be used to produce carbon fibers by direct electrospinning, without blending with another polymer to reduce breakage. Analyses have shown that the carbon obtained from PCFA is superior to that obtained from other lignins. The fibers formed from PCFA are smoother, have a narrower diameter distribution, and show very low defects. The PCFA can be obtained by extraction from plant seed coats. Examples of these plants include the vanilla orchid, Vanilla planifolia, and Jatropha curcas. The fibers may be formed through electrospinning, although other methods for forming the fibers, such as extrusion with a carrier polymer, could be used. The fibers may then be carbonized to increase the carbon yield.

  • Patent number: 9761660
    Abstract: Manufacturable spin and spin-polaron interconnects are disclosed that do not exhibit the same increase in resistivity shown by Cu interconnects associated with decreasing linewidth. These interconnects rely on the transmission of spin as opposed to charge. Two types of graphene based interconnect approaches are explored, one involving the injection and diffusive transport of discrete spin-polarized carriers, and the other involving coherent spin polarization of graphene charge carriers due to exchange interactions with localized substrate spins. Such devices are manufacturable as well as scalable (methods for their fabrication exist, and the interconnects are based on direct growth, rather than physical transfer or metal catalyst formation). Performance at or above 300 K, as opposed to cryogenic temperatures, is the performance criteria.

  • Patent number: 9624600
    Abstract: Direct growth of graphene on Co3O4(111) at 1000 K was achieved by molecular beam epitaxy from a graphite source. Auger spectroscopy shows a characteristic sp2 carbon lineshape, at average carbon coverages from 0.4-3 monolayers. Low energy electron diffraction (LEED) indicates (111) ordering of the sp2 carbon film with a lattice constant of 2.5 (±0.1) ? characteristic of graphene. Six-fold symmetry of the graphene diffraction spots is observed at 0.4, 1 and 3 monolayers. The LEED data also indicate an average domain size of ˜1800 ?, and show an incommensurate interface with the Co3O4(111) substrate, where the latter exhibits a lattice constant of 2.8 (±0.1) ?. Core level photoemission shows a characteristically asymmetric C(1s) feature, with the expected lr to lr* satellite feature, but with a binding energy for the three monolayer film of 284.9 (±0.1) eV, indicative of substantial graphene-to-oxide charge transfer.

  • Patent number: 9574263
    Abstract: A soft-landing (SL) instrument for depositing ions onto substrates using a laser ablation source is described herein. The instrument of the instant invention is designed with a custom drift tube and a split-ring ion optic for the isolation of selected ions. The drift tube allows for the separation and thermalization of ions formed after laser ablation through collisions with an inert bath gas that allow the ions to be landed at energies below 1 eV onto substrates. The split-ring ion optic is capable of directing ions toward the detector or a landing substrate for selected components. The inventors further performed atomic force microscopy (AFM) and drift tube measurements to characterize the performance characteristics of the instrument.

  • Patent number: 9564579
    Abstract: A Tunnel Magnetic Junction of high magnetoresistance is prepared at temperatures and pressure consistent with Si CMOS fabrication and operation. A first metal layer of cobalt or nickel is grown on an interconnect or conductive array line of e.g., copper. The metal layer is formed by electron beam irradiation. Annealing at UHV at temperatures below 700K yields a carbon segregation that forms a few layer thick (average density 3.5 ML) graphene film on the metal layer. Formation of a second layer of metal on top of the graphene barrier layer yields a high performance MTJ.

  • Patent number: 9523925
    Abstract: A single reflective optical element is constructed for use in interference lithography. The single reflective optical element is generally made up of at least two, and preferably four, polished reflective strips arranged to have particular angles relative to a laser beam passing through the optical element. A laser beam passing through the optical element will be partially reflected by the reflective strips to generate additional linearly polarized beams. The additional reflected beams overlap with the central laser beam and form an interference pattern as the beams pass out of the optical element. The generated polarized beams and interference pattern can be directed onto a photosensitive material to produce photonic crystals or photonic crystal templates.
