Abstract: A device stack for an electronic memory or other device includes a substrate and first and second layers of insulating material. The first layer of insulating material is supported by the substrate. A semiconducting ferroelectric layer is positioned and electrically isolated between the first and second layers of insulating material. A stress layer capable of converting a ferroelectric or semiconductor material into a semiconducting ferroelectric material can be positioned in contact with the semiconducting ferroelectric layer. In some embodiments, the device is a Metal-Insulator-FeS-Insulator-Semiconductor (MIFIS) device that allows for controlled switching of the semiconducting ferroelectric (FeS) layer between various polarization states. Switching polarization states is enabled by application of an electric field by a semiconducting electrode.

Abstract: Subject matter disclosed herein may relate to fabrication of a correlated electron material (CEM) such as in a CEM device capable of switching between and/or among impedance states. In particular embodiments, a CEM may be formed from one or more transition metal oxides (TMOs), one or more post transition metal oxides (PTMOs) or one or more post transition metal chalcogenides (PTMCs), or a combination thereof.

Abstract: Methods are disclosed herein for controlling the switching characteristics of correlated electron material (CEM) switching devices. The methods comprise one or more of controlling a density of grain boundaries in the CEM layer, controlling an open pore porosity in the CEM layer and controlling a surface area of exposed surfaces of the CEM layer during the fabrication of the CEM switching devices.

Abstract: Briefly, embodiments of claimed subject matter relate to devices and methods for formation of ferroelectric materials utilizing transition metals, transition metal oxides, post transition metals, and/or post transition metal oxides, which may be doped with bismuth (Bi) in a concentration of between about 0.001% to about 25.0%. Alternatively, a dopant may include bismuth oxide (Bi2O3) or may include bismuth aluminum oxide ((BixAl1?x)2O3). In particular embodiments, such utilization of bismuth and/or related dopants may bring about stabilization of relatively thin ferroelectric devices.
