Abstract
Subject matter herein disclosed relates to an improved CEM switching device and methods for its manufacture. In this device, a conductive substrate and/or conductive overlay comprises a primary layer of a conductive material and a secondary layer of a conductive material. The primary layer contacting the CEM layer is substantially inert to the CEM layer and/or acts as an oxygen barrier for the secondary layer at temperatures used for the manufacture of the device.
Claims14
A method for the manufacture of a CEM switching device, which method comprises forming a conductive substrate, forming a layer of a correlated electron material (CEM) on the conductive substrate and forming a conductive overlay on the CEM layer, wherein the forming the conductive overlay comprises forming a primary layer of a conductive material contacting the CEM layer and forming a secondary layer of a conductive material on or over the primary layer and the forming of the conductive substrate comprises forming a secondary layer of a conductive material on a substrate and forming a primary layer of a conductive material on the secondary layer wherein the thickness of the secondary layer is greater than that of the primary layer and wherein the conductive material of the primary layer is substantially resistant to diffusion or migration of oxygen ion from the CEM layer to the secondary layer.
A switching device comprising a conductive substrate, a conductive overlay and a layer of a correlated electron material (CEM) therebetween wherein the conductive substrate and the conductive overlay each comprises a primary layer of a conductive material and a secondary layer of a conductive material wherein the thickness of the secondary layer is greater than that of the primary layer and wherein the primary layer contacts the CEM layer and is substantially resistant to diffusion or migration of oxygen ion from the CEM layer to the secondary layer.
