摘要:
At least two types of dielectric materials such as oxide nanosheets having a layered perovskite structure that differ from each other are laminated, and the nanosheets are bonded to each other via an ionic material, thereby producing a superlattice structure-having ferroelectric thin film. Having the layered structure, the film can exhibit ferroelectricity as a whole, though not using a ferroelectric material therein. Accordingly, there is provided a ferroelectric film based on a novel principle, which is favorable for ferroelectric memories and others and which is free from a size effect even though extremely thinned.

Provided is an electromagnetic wave absorbent material comprising a magnetic film as the main constituent thereof. The magnetic film comprises a titania nanosheet where a 3d magnetic metal element is substituted at the titanium lattice position. The electromagnetic wave absorbent material stably and continuously exhibits electromagnetic wave absorption performance in a range of from 1 to 15 GHz band and is useful as mobile telephones, wireless LANs and other mobile electronic instruments. The absorbent material can be fused with a transparent medium and is applicable to transparent electronic devices such as large-sized liquid crystal TVs, electronic papers, etc.

摘要:
A monolayer or a multilayer of niobic acid nanosheets is attached to form a dielectric film, and other electrode is arranged on the surface of the dielectric film to construct a dielectric element, and the dielectric element thus provided realizes both high permittivity and good insulating properties even in a nano-region. Also provided is a method of producing the element at low temperatures with no influence of substrate interface deterioration and composition deviation thereof. The method entirely solves the problems of substrate interface deterioration and the accompanying composition deviation and electric incompatibility, and solves the intrinsic problem of “size effect” that the film thickness reduction to a nano-level lowers the specific permittivity and increases the leak current, and the method takes advantage of the peculiar properties and good ability of texture and structure regulation that the niobic acid nanosheet has.

Provided is a dielectric element comprising a dielectric thin film formed of a layer of perovskite nanosheets. The dielectric element has the advantages of inherent properties and high-level texture and structure controllability of the perovskite nanosheets, therefore realizing both a high dielectric constant and good insulating properties in a nano-region.

摘要:
To provide a method for producing a thin film consisting of nanosheet monolayer film(s) and use of the thin film obtained thereby.The method for producing a thin film consisting of nanosheet monolayer film(s) by a spin coat method according to the invention comprises a step for preparing an organic solvent sol formed by allowing nanosheets obtained by the exfoliation of an inorganic layered compound to be dispersed in an organic solvent; and a step for dropping the organic solvent sol onto a substrate and rotating the substrate using a spin coater. Preferably, the nanosheet size, the organic solvent sol concentration and the spin coater rotation speed are controlled.
