発明の名称 (英語) NOVEL DIELECTRIC MATERIAL 新技術説明会
発明の概要(英語) Provided are a new dielectric material and an electrostrictive material. The dielectric material or electrostrictive material comprises a charge separated-type non-coulombic ionic solid in which complex cations comprising metal elements and ligands are integrated forming cation clusters, the cation clusters being arranged in a closest packing structure with vacancies in which anions are integrated, forming anion clusters.
従来技術、競合技術の概要(英語) BACKGROUND ART
Have a dielectric constant, capacitor, semiconductor device, such as an optical fiber has been widely applied. For example, barium titanate having a perovskite structure, has a very high dielectric constant ceramic as a dielectric material of the multilayer capacitor has been widely used.
In addition, to decrease electrical resistance as the temperature rises as the thermistor, the temperature is raised slowly NTC(negative temperature coefficient) to decrease electrical resistance of the thermistor, and temperature in the thermistor resistance decreases rapidly and exceeds the CTR(critical temperature resistor). NTC thermistor may be, nickel, manganese, and iron oxide sintered body is used. CTR thermistor may be a, the vanadium oxide by sintering additive is added is used. However, the thermistor NTC is, the temperature rise in a gradual decrease in the electrical resistance can be used from the limited fields. On the other hand, the current CTR thermistor is used, the initial electric resistance value is generally not sufficiently high, depending on the value of the resistance of the circuit because of the types does not operate, the method used is limited. In addition, electrical resistance changes due to a temperature rise 103 about twice, the thermostat control circuit such as the problem of low performance or the like. Further, the thermistor is used as a thermometer, a thermistor NTC is gradual decrease in electrical resistance from the temperature detection precision cannot be sufficiently, CTR thermistor is narrow in a temperature range for rapid resistance change, a certain temperature in regions other than the thermometer as a problem that significantly lowers sensitivity.
In addition, the piezoelectric material is a kind of dielectric material, when the electric field is applied to a reverse distortion of the electrostrictive material and the piezoelectric, electro-mechanical energy conversion element has been widely used as an actuator. Such as a electrostrictive material, for example, lead zirconate titanate (PZT) or the like has been used (Non-Patent Document 1). Has been developed a conventional reverse piezoelectric type is an exemplary an electrostrictive material, the direction of voltage application in the same direction and the driving direction, in order to operate the other direction must be incorporated in the gear and the like.
On the other hand, the inventors of the present invention, ionic solids and an entirely new function in order to produce various investigations, Au4 Co2 (dppe)2 (D-pen)4 (ClO4)2, qH2 Osuccessful creation of. This ionic solids, ionic solids present in the natural world is different from the, ion pairs but rather, non-ionic clusters and becomes solid by the charge separation type kuronka ionic solid (non-patent document 2) has been found.
