摘要:
A high dielectric nanosheet laminate is produced by laminating nanosheets, each of which has a thickness of 10 nm or less and is formed of an oxide that has a perovskite structure wherein at least four NbO6 octahedrons, TaO6 octahedrons or TiO6 octahedrons are included in a unit lattice. Consequently, the high dielectric nanosheet laminate is capable of achieving a high dielectric constant and a satisfactory insulation property, which are preferable for high dielectric nanosheet multilayer capacitors or the like, at the same time even if formed very thin.
摘要:
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:
A magnetic artificial superlattice is composed of laminated thin films including two or more kinds of magnetic flaky particles (magnetic titania nanosheets) obtained by exfoliation of a layer titanium oxide in which Ti atoms in the lattice have been substituted with magnetic elements.

摘要:
A substrate for surface enhanced Raman spectroscopy analysis (SERS) comprises a ferroelectric single crystal having polarization-inverted patterns of spontaneous polarizations including polarization-inverted portions and non-inverted polarization portions, and metallic dots positioned at only either one polarized surfaces of the polarization-inverted portions and the non-inverted polarization portions. The provided SERS substrate produces a high enhancement effect. A microfluidic device incorporating the SERS substrate is also provided.
