Abstract:
1. A cross-point cell nanoarray comprising: a mechanical support substrate; a first plurality of electrodes defined over an area of the substrate, the electrodes of the first plurality being substantially uniformly spaced and substantially parallel to each other; a second plurality of electrodes substantially orthogonal to the electrodes of said first plurality, the electrodes of the second plurality being substantially uniformly spaced and substantially parallel to each other, the first and second pluralities of electrodes being configured to define cross-points each being a location at which a respective electrode of the first plurality of electrodes crosses a respective electrode of the second plurality of electrodes; and an active organic resin layer positioned between said first plurality of electrodes, the active organic resin layer having dispersed therein conductive nanoparticles and/or conductive nanoparticle clusters, said active organic resin layer comprising a matrix block copolymer of a major component resin and of at least one different minor component resin, the matrix block copolymer being configured to form large-scale ordered nanostructures through phase segregation due to block incompatibility and self-assembly properties of blocks of the matrix block copolymer, said ordered nanostructures of the matrix block copolymer being configured to sequester the conductive nanoparticles and/or conductive nanoparticle clusters by subtracting them from a surrounding matrix of the matrix copolymer, wherein said ordered nanostructures are parallel nanostructures, with axes substantially orthogonal to surfaces of the first plurality of electrodes that face corresponding surfaces of the second plurality of electrodes at the crossing points, and define preferential electric current paths across the active organic resin layer.
