    Abstract: A conductive channel formed of an (Sm, Ce)Al11O18 is interconnected in the grain boundaries of aluminum nitride (AlN) particles, thereby reducing temperature dependency of volume resistivity of AlN sintered body; at the same time, the solid solution of the AlN particles is formed with at least one of C and Mg, to prevent the conductive channel from moving in AlN particles, thereby maintaining the volume resistivity within AlN particles at a high value even at a high temperature.

  • Publication number: 20070215843
    Abstract: The invention provides simplified negative index materials (NIMs) using wire-pair structures, 4-gap single ring split-ring resonator (SRR), fishnet structures and overleaf capacitor SRR. In the wire-pair arrangement, a pair of short parallel wires and continuous wires are used. In the 4-gap single-ring SRR, the SRRs are centered on the faces of a cubic unit cell combined with a continuous wire type resonator. Combining both elements creates a frequency band where the metamaterial is transparent with simultaneously negative ? and ?. In the fishnet structure, a metallic mesh on both sides of the dielectric spacer is used. The overleaf capacitor SRR changes the gap capacities to small plate capacitors by making the sections of the SRR ring overlap at the gaps separated by a thin dielectric film. This technique is applicable to conventional SRR gaps but it best deploys for the 4-gap single-ring structures.

  • Publication number: 20070215859
    Abstract: A thin blanket epitaxial layer of SiGe is grown on a silicon substrate to have a biaxial compressive stress in the growth plane. A thin epitaxial layer of silicon is deposited on the SiGe layer, with the SiGe layer having a thickness less than its critical thicknesses. Shallow trenches are subsequently fabricated through the epitaxial layers, so that the strain energy is redistributed such that the compressive strain in the SiGe layer is partially relaxed elastically and a degree of tensile strain is induced to the neighboring layers of silicon. Because this process for inducing tensile strain in a silicon over-layer is elastic in nature, the desired strain may be achieved without formation of misfit dislocations.

An n-type layer is made of a group-III nitride, and a p-type layer is made of a group-IV semiconductor material having a smaller band gap than the group-III nitride. The energy level at the top of the valence band of the n-type layer is lower than the energy level at the top of the valence band of the p-type layer, so that a P—N junction semiconductor device satisfying the above requirements is obtained. Further, a combined structure of P—N junction and Schottky junction by additionally providing an anode electrode to be in Schottky contact with the n-type layer also achieves the effect of decreasing voltage at the rising edge of current resulting from the Schottky junction.
