Thin films of lithium-containing materials and methods for fabricating them are generally described. In some embodiments, the formation of a first vapor is induced from a first target and the formation of a second vapor is induced from a second target, resulting in the formation of a thin film. In some embodiments, at least a portion of the formation of the first vapor and the formation of the second vapor occurs under vacuum conditions. In some embodiments, the thin film has a relatively high ionic conductivity, mixed ionic/electronic conductivity, or other properties beneficial for applications such as active electrode materials or solid-state electrolytes.

Methods of fabricating thin films comprising lithium-containing materials

Resistive switching devices that contain lithium, including resistive switching devices containing a lithium titanate, and associated systems and methods are generally described. In some cases, the resistive switching device contains a lithium titanate-containing domain, a first electrode, and a second electrode. In some cases, the application of an electrical potential to the resistive switching device causes a change in resistance state of the lithium titanate-containing domain. The resistive switching devices described herein may be useful as memristors, and in applications that include Resistive-random access memory and neuromorphic computing.

Solid-state electrolyte and method of manufacture thereof

An optoelectronic memristor includes a first electrode, a second electrode, and a solid electrolyte in between that is in electrical communication with the first electrode and the second electrode. The solid electrolyte has an electronic conductivity of about 10Siemens/cm to about 10Siemens/cm at room temperature. The first electrode, and optionally the second electrode, can be optically transparent at a specific wavelength and/or a wavelength range. A direct current (DC) voltage source is employed to apply an electric field across the solid electrolyte, which induces a spatial redistribution of ionic defects in the solid electrolyte. In turn, this causes a change in electrical resistance of the solid electrolyte. The application of the electric field can also cause a change in an optical property of the solid electrolyte at the specific wavelength, and/or at the wavelength range (or a portion thereof).
