20100155690 | CROSS-POINT CELL NANOARRAY WITH ANISOTROPIC ACTIVE ORGANIC LAYER - A cross-point cell nanoarray comprises a mechanical support substrate, first and second orders of uniformly spaced parallel electrodes separated by an electrically active organic film and orthogonally arranged to form an array of cross-point cells, individually addressable by biasing the respective opposite electrodes, by selecting them among those of the respective orders, over a planar area of the substrate. The active organic resin layer includes a block copolymer of a major component resin and of at least one different minor component resin, configured to promote formation of large-scale ordered nanostructures through phase segregation, due to block incompatibility and self-assembly properties of the blocks. Polymeric bocks of the ordered nanostructures configured to sequester conductive nanoparticles and/or conductive nanoparticle clusters originally dispersed in the component organic resins, subtracting them from the surrounding matrix copolymer. Preferential electric current paths across the thickness of the active organic layer at cross-over points are thus created. | 06-24-2010 |
