  • Publication number: 20070224399
    Abstract: The presently disclosed invention provides for the fabrication of porous anodic alumina (PAA) films on a wide variety of substrates. The substrate comprises a wafer layer and may further include an adhesion layer deposited on the wafer layer. An anodic alumina template is formed on the substrate. When a rigid substrate such as Si is used, the resulting anodic alumina film is more tractable, easily grown on extensive areas in a uniform manner, and manipulated without danger of cracking. The substrate can be manipulated to obtain free-standing alumina templates of high optical quality and substantially flat surfaces PAA films can also be grown this way on patterned and non-planar surfaces. Furthermore, under certain conditions the resulting PAA is missing the barrier layer (partially or completely) and the bottom of the pores can be readily accessed electrically.

  • Publication number: 20060113569
    Abstract: A field effect transistor (FET) includes a substrate, and a gate layer formed on the substrate. An oxygen plasmarized polymeric gate dielectric is formed on the gate layer so as to increase the threshold voltage of the OFET. A semiconductor layer is formed on the oxygen plasmarized polymeric gate dielectric.

  • Publication number: 20060076584
    Abstract: A transfer layer includes a transparent substrate. A buffer layer is formed on the transparent substrate that comprises PbO, GaN, PbTiO3, La0.5Sr0.5CoO3 (LSCO), or LaxPb1-xCoO3 (LPCO) so that separation between the buffer layer and the transparent substrate occurs at substantially high temperatures.
