Abstract: Resistive switching memory elements are provided that may contain electroless metal electrodes and metal oxides formed from electroless metal. The resistive switching memory elements may exhibit bistability and may be used in high-density multi-layer memory integrated circuits. Electroless conductive materials such as nickel-based materials may be selectively deposited on a conductor on a silicon wafer or other suitable substrate. The electroless conductive materials can be oxidized to form a metal oxide for a resistive switching memory element. Multiple layers of conductive materials can be deposited each of which has a different oxidation rate. The differential oxidization rates of the conductive layers can be exploited to ensure that metal oxide layers of desired thicknesses are formed during fabrication.

Abstract: A method of dispersing particles in a medium. The method includes providing a first particle/solvent dispersion comprising the particles and a first solvent, adding a second solvent to the first particle/solvent dispersion to form a second particle/solvent dispersion, wherein the first solvent and the second solvent are miscible, and extracting substantially all of the first solvent from the second particle/solvent dispersion to form a third particle/solvent dispersion.
