摘要： Superconducting transition metal oxide films are provided which exhibit very high onsets of superconductivity and superconductivity at temperatures in excess of 40K. These films are produced by vapour deposition processes using pure metal sources for the metals in the superconducting composition, where the metals include multi-valent nonmagnetic transition metals, rare earth elements, and/or rare earth-like alkaline earth elements. The substrate is exposed to oxygen during vapour 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, Ca, Ba, and Sr.

摘要： 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 100µA/cm 2 to 500mA/cm 2 , 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.

摘要： In a method of fabricating a layered ribbon structure (24), metal, such as copper, iron, iron alloy or silver, is melted in a crucible (4) by an RF heater (8) and ejected through a nozzle (10) by inert gas supplied under pressure through a pipe (18) and regulated by a valve (22). The stream of molten metal from the nozzle is directed at a small angle to the vertical upon the crest of a rotating wheel (14) to generate a moving ribbon (11). A dissimilar material of lower melting point, such as a semiconductor material, silicon, germanium or gallium arsenide, is melted in a second crucible (2) by an RF heater (6) and ejected through a nozzle (12) by inert gas supplied under pressure through a pipe (16) and regulated by a valve (20).
The stream of molten semiconductor material is directed parallel to the stream of molten metal upon the moving ribbon of metal to generate a ribbon (13) which forms a second layer of layered ribbon structure (24). The method may be used for the mass production of semiconductor devices such as diodes, solar cells and the like.
