Abstract:
A composite material is provided by this disclosure which utilizes prior art host matrix materials with new resident inclusions for structural members with unique properties and applications. An illustrative embodiment of a composite material according to the principles of this invention is described with fiber inclusions fabricated by electroplating of a polycrystalline film on a substrate. Polycrystalline fibers are fabricated with a wide range of sizes to have strength approaching those of a single crystal whisker of the polycrystalline material. An illustrative composite material is fabricated with a host matrix of epoxy resin in which resident fiber inclusions are dispersed.

A method of assembling a circuit includes providing a template, enabling a semiconductor material to self assemble on the template, and enabling self-assembly of a connection between the semiconductor material and the template to form the circuit and a circuit created by self-assembly.
Abstract:
Liquid crystals on a polymer (eg polyimide) surface are aligned by exposure to a low energy and neutral Argon ion beam. The energy of the incident ions were varied between 75 and 500 eV, the integrated current density from 100 mu A/cm to 500mA/cm , and the angle of incidence over which alignment was measured was between 10 and 80 degrees. The pretilt angle of the liquid crystals could be varied between 0 and 8 degrees, by controlling the processing conditions. Degradation of the polyimide, which leads to charge migration, can be avoided by operating at low accelerating voltages.

PROBLEM TO BE SOLVED: To provide a molecule manipulator, a method for manufacturing the same, and a method for moving a nano-structure. SOLUTION: The molecule manipulator includes photoreactive molecules including a double bond and changes a cis-trans arrangement of the double bond in reaction by the irradiation by the light of the selected wavelength, and a probe with the photoreactive molecules fitted thereto, for example, a probe of a scanning proximity probe microscope. A method for manufacturing the molecule manipulator includes a step of forming a covalent bond of the photoreactive molecules with the probe. A method for moving a nano-structure includes a step of controllably holding the nano-structure by the molecule manipulator, a step of moving the nano-structure, and a step of releasing the nano-structure.

Abstract:
A method for preparing a alignment layer surface provides a surface on the alignment layer. A chemically modified surfae [117] is formed as a result of quenching and/or ion beam treatment in accordance with the present invention, and reactive gas is introduced to the ion beam to saturate dangling bonds on the surface. Layer [117] is now substantially free from dangling bonds and free radicals which could degrade properties of a liquid crystal display. Now, a substrate [101] is formed for use in a liquid crystal displax device. Another method for preparing an alignment layer. The surface is bombarded with ions and quenched with a reactive component to saturate dangling bonds on the surface.
Abstract:
Superconducting transition metal oxide films are provided which exhibit very high onsets of superconductivity and superconductivity at temperatures in excess of 40.degree.K. These films are produced by vapor deposition processes using pure metal sources for the metals in the superconducting compositions, where the metals include multi-valent nonmagnetic transition metals, rare earth elements, and/or rare earth-like elements and alkaline earth elements. The substrate is exposed to oxygen during vapor deposition, and, offer formation of the film, ambient followed by at least one annealing step in an oxygen ambient and slow cooling over several hours to room temperature. The substrates chosen are not critical as long as they are not adversely reactive with the superconducting oxide film. Transition metals include Cu, Ni, Ti, and V, while the rare earth-like elements include Y, Sc, and La. The alkaline earth elements include Ca, Ba, and Sr.
Abstract:
A field-effect structure, formed on a substrate (20) and comprising a channel (21) with source (22) and drain (23) as well as a gate (25) that is separated from the channel by an insulating layer (24). The channel is made of a high-Tc metal-oxide superconductor, e.g., YBaCuO, having a carrier density of about 10 /cm and a correlation length of about .2 nm. The channel thickness is in the order of 1 nm, it is single crystalline and oriented such that the superconducting behaviour is strongest in the plane parallel to the substrate. With a signal of a few Volt applied to the gate, the entire channel cross-section is depleted of charge carriers whereby the channel resistance can be switched between "zero" (undepleted, superconducting) and "very high" (depleted).
