  • Read/write tip, head and device, and use thereof, and method for manufacturing same
    Patent number: 8040784
    Abstract: The invention concerns a reading/writing tip configured in the shape of a needle consisting of a core of refractory material covered with a coating of electrically conductive material, and having an outer microscope needle geometry by tunnel effect, to obtain an information concerning a surface through tunnel-effect microscopy The needle emits a charged particle from the layer of electrically conductive material, to form the surface. The tip comprises a reservoir capable of being liquefied to flow along the tip.
    Type: Grant

  • Juxtaposed island manufacturing method by means of self-organised deposition on a substrate and structure obtained using said method
    Patent number: 7285378
    Abstract: The invention relates to a structure composed of a substrate wherein a surface supports juxtaposed islands, characterized in that the islands rest on a periodic network of terraces composed of the intersection of two step networks, each terrace having a first dimension corresponding to the step width of one of the step networks and a second dimension corresponding to the step width of the other step network, each terrace supporting at least two islands formed of a different superimposition of monolayers wherein the composition is chosen between at least one first composition and one second composition.
