Patent ID: 8222077

Claim:
A method of forming a vertical two-terminal switching device comprising: (a) forming a first electrode of the vertical two-terminal switching device on a substrate, wherein the first electrode comprises a metal layer being characterized by a first work function value; (b) forming a layer of an inorganic insulator or broad band semiconductor, over at least a portion of the first electrode, wherein forming the layer of the inorganic insulator or broad band semiconductor comprises anodizing, thermally oxidizing or plasma oxidizing at least a portion of the metal layer; and (c) forming a second electrode by forming a layer of a second conductive material overlaying at least a portion of the layer of an inorganic insulator or broad band semiconductor and residing over at least a portion of the first electrode, wherein the second conductive material is characterized by a second work function value, and wherein forming the second electrode comprises depositing a liquid-phase material.
