The invention relates to thin film single layers, electronic components such as multilayer capacitors which utilize thin film layers, and to their methods of manufacture. Chemical solution deposition and microcontact printing of dielectric and electrode layers are disclosed. High permittivity BaTiO3 multilayer thin film capacitors are prepared on Ni foil substrates by microcontact printing and by chemical solution deposition. Multilayer capacitors with BaTiO3 dielectric layers and LaNiO3 internal electrodes are prepared, enabling dielectric layer thicknesses of 1 μm or less. Microcontact printing of precursor solutions of the dielectric and electrode layers is used.

摘要:
A thin film comprising a pyrochlore represented by the formula: (Bi3xZn2−3x)(ZnxNb2−x)O7 wherein x is from about 0.45 to about 0.73 and an article comprising a substrate and, coated on the substrate, a thin film of the pyrochlore are provided. Also provided is a process for depositing on a substrate the above pyrochlore thin film. The process includes the steps of coating the substrate with a composition comprising bismuth carboxylate, zinc carboxylate, niobium alkoxide, an organic solvent, an organic acid and an organic base, heating to remove organic components and annealing at a temperature and for a length of time sufficient to produce the pyrochlore thin film on the substrate.

A piezoelectric ultrasonic motor having 2-dimensional positioning movement includes a stator. The stator includes a piezoelectric ceramic bar and an electrode disposed on the bar. Each bar includes two wings that are separated by a predetermined angle to form a predetermined shape. A power source is used to apply a voltage to the stator to excite a bending mode vibration in the each of the wings, and the combined motion of the two wings produces an elliptical motion at a tip of the wing. A load is operatively connected to the stator, such that a portion of the load in contact with the stator is driven to move linearly through a frictional force between the load and the stator, due to the elliptical motion at the tip of the wing.

The present invention is directed to a new family of high Curie temperature, morphotropic phase boundary systems, based on the perovskite solid solution having the general formula (1−x)BiMeO3-xPbTiO3, where Me is a suitably sized cation or combination of cations and x is a molar fraction. The perovskite systems of the present invention offer room temperature properties analogous to, and high temperature properties superior to, commercially available PZT compositions. The perovskite of this invention exhibits a MPB between the rhombohedral and tetragonal phases. Further dopant strategies may be used for property optimization of the perovskite systems.
摘要:
Co-fired multilayer piezoelectric ceramic materials with base metal electrodes based on copper, copper alloy, are found as an effective approach to manufacture low cost multilayer piezoelectrics. The method of the invention is performed at low firing temperature and without the oxidation of base metal or reduction of ceramic components. A variety of ceramic materials may be used and copper is the preferred base metal in the multi-layer piezoelectric devices of the invention. This copper has additional protection against oxidation with a small inorganic coating on the surface. With such protection, the binder and other organics can also be efficiently removed and produce superior performance in the piezoelectric structured devices.

摘要:
A method for deposition of an electrolyte material on a porous substrate in which a suspension of particles having a controlled surface charge and suitable for use as an electrolyte is formed and the porous substrate, which is made of an electrode material is immersed. A voltage is applied across the suspension between an electrode in contact with the suspension and the porous substrate, whereby at least a portion of the particles migrate toward the porous substrate and are deposited on the porous substrate.
