Title:
MATERIALS WITH TUNABLE PROPERTIES AND MEMORY DEVICES AND METHODS OF MAKING SAME USING RANDOM NANOWIRE OR NANOTUBE NETWORKS
Document Type and Number:
WIPO Patent Application WO/2013/164467
Kind Code:
A3
Abstract:
A device comprising a first electrode; a second electrode; and an active material positioned between the first and second electrode, wherein the active material comprises a plurality of randomly positioned conducting wires coated with a nanoscale switchable dielectric layer, said conducting wires are adapted to provide a conducting path or paths when a voltage is applied by one of the electrodes or between said electrodes.
