Electronic and optical (or photonic) devices with variable or switchable properties and methods used to form these devices, are disclosed. More specifically, the present invention involves forming layers of conductive material and dielectric material or materials with varying conductivity and indexes of refraction to form various electronic and optical devices. One such layer of adjustable material is formed by depositing epitaxial or reduced grain boundary barium strontium titanate on the C-plane of sapphire.

Electronic and optical devices and methods of forming these devices

Capacitor material for use in forming capacitors, is disclosed. More specifically, the invention is directed to capacitors formed from this material that have one or more discrete electrodes (), each electrode () being exposed to at least two thicknesses of dielectric material (). These electrodes () are surrounded by wider insulative material () such that the material can be cut, or patterned into capacitors having specific values. A single electrode can form a small value capacitor while still providing a larger conductive area for attaching the capacitor to associated circuitry. The thin dielectric () can be a tunable material so that the capacitance can be varied with voltage. The tunability can be increased by adding thin electrodes that interact with direct current.
