Abstract: A NEW COMPOUND WITH ROOM-TEMPERATURE ELECTRICAL RESISTIVITY COMPARABLE TO THAT OF ELEMENTAL COPPER The present invention relates to novel compounds that exhibit unusually low electrical resistivity at room temperature. More specifically, it has been discovered that the incorporation of at least 1 to 15 atomic percent of gallium and/or at least 1 to 15 atomic percent gold into stoichiometric copper germanide (Cu3Ge) compound results in a room temperature resistivity comparable to elemental copper, but with superior chemical and electronic stability upon exposure to air or oxygen at high temperatures. Furthermore, the compounds of the present invention have none of the problems associated with the diffusion of copper into elemental and compound semiconductors which oftentimes lead to the degradation of the semiconductor device characteristics. Additionally, the present invention relates to a method of preparing the novel compounds mentioned previously hereinabove.

Abstract: The cathodes in a D.C. gas discharge panel are isolated from the gas by a layer of refractory material doped with a noble metal. The doping is sufficient to prevent the build-up of a surface wall charge on the layer during D.C. operation of the panel. Ki9-77017

Abstract: A D.C. gaseous discharge display panel operated in a storage mode uses a layer of resistive material over the cathodes of the display. In addition to protecting the electrodes from ion bombardment induced sputtering during discharge, the material provides a resistance to each discharge cell, provides isolation between individual cathodes by reducing discharge spreading along the cathode conductors and prevents surface charge building during panel operation. By utilizing a combination of metal and insulator in the resistance layer, the D.C. discharge can be sustained at lower operating voltage, permitting a reduction in the power requirements of the panel.
