In some examples, a system comprises a capacitor including a first plate, a second plate, and a ferroelectric material disposed between the first and the second plates and comprising a Bismuth Metal Oxide-Based Lead Titanate thin film. The capacitor further comprises a dielectric layer disposed on a transistor, wherein the capacitor is disposed on the dielectric layer.

Methods for making metastable lead-free piezoelectric materials are presented herein.

High breakdown strength ferroelectric SrHfOmaterials

Both single phase lead-free cubic pyrochlore bismuth zinc niobate (BZN)-based dielectric materials with a chemical composition of BiZnNbTaO, with 0&#x2266;x&#x3c;0.23 and 0&#x2266;y&#x3c;0.9 and films with these average compositions with BiOparticles in an amorphous matrix and a process of manufacture thereof. The crystalline BZNT-based dielectric material has a relative permittivity of at least 120, a maximum applied electric field of at least 4.0 MV/cm at 10 kHz, a maximum energy storage at 25&#xb0; C. and 10 kHz of at least 50 J/cmand a maximum energy storage at 200&#xb0; C. and 10 kHz of at least 22 J/cm. The process is a wet chemical process that produces thin films of BiZnNbTaOwithout the use of 2-methoxyethanol and pyridine.

An example ultrasound device, such as a transducer array, includes a plurality of ultrasound transducers, each ultrasound transducer having a first electrode, a second electrode, a thin piezoelectric film located between the electrodes, and a substrate supporting the plurality of ultrasound transducers. In some examples, the electrode separation is less than 10 microns, facilitating lower voltage operation than conventional ultrasound transducers.

The disclosed invention relates to unsupported, anisotropically shaped, cubic SrTiO single crystal particles and their method of manufacture. The particles have a rectangular face and measure about 10-40 micron in edge length, and about 2-5 micron in thickness. The anisotropically shaped, cubic SrTiO single crystal particles are made by reacting tabular Sr Ti O with TiO in the presence of a molten alkali salt.
