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.
Claims20
A method for the manufacture of a CEM switching device, which method comprises forming a conductive substrate and forming a layer of a correlated electron material (CEM) on the conductive substrate, wherein the forming of the conductive substrate comprises forming a primary layer of a conductive material and forming a secondary layer of a conductive material such that the primary layer contacts the CEM layer and wherein the forming of 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, and a layer of a correlated electron material (CEM), wherein the conductive substrate comprises a primary layer of a conductive material and a secondary layer of a conductive material 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.
