摘要:
PROBLEM TO BE SOLVED: To provide a method of manufacturing nano-wires which are grown by controlling diameters and distribution of nano-wires, and nano-wires accurately grown using the method. SOLUTION: The method of manufacturing the nano-wires includes (1) a step for forming microgrooves having a plurality of microcavities regularly on the surface of a silicon substrate, (2) a step for forming a metal layer on the silicon substrate by depositing a material which acts as a catalyst to form nano-wires on the silicon substrate, (3) a step for agglomerating the metal layer within the microgrooves on the surface of the silicon substrate by heating the metal layer to form catalysts and (4) a step for growing the nano-wires between the catalysts and the silicon substrate using a thermal process.

摘要:
A magnetic nanoparticle (22), a magnetic nanomaterial (30), assembly (30), and a method for synthesising a magnetic nanoparticle, relating to thermodynamically stable and air stable ferromagnetic nanoparticles of adjustable aspect ratio made upon decomposition of organometallic precursors in solution in the presence of a reaction gas and a mixture of organic ligands. The magnetic nanomaterial comprises magnetic nanoparticles of homogeneous size, shape, and magnetic orientation that comprises a magnetic core (24,34) ferromagnetic at room temperature and/or operating temperatures, and a nonmagnetic matrix (26,36) encapsulating the magnetic core. This magnetic nanomaterial could be used in high frequency integrated circuit applications, such as used in wireless portable electronic devices, to enhance magnetic field confinement and improve passive component performance at MHz and GHz frequency in a variety of passive and active devices, such as transformers, on-chip signal isolation, inductors, and the like.

PROBLEM TO BE SOLVED: To provide an optical member which can be produced with high productivity and includes an antireflection film having sufficient optical characteristics.SOLUTION: The optical member includes an antireflection film 19 comprising a transparent thin film layer 15 and a transparent finely rugged layer 18 essentially comprising an alumina hydrate, disposed in this order on a surface of a transparent substrate 10. The transparent thin film layer 15 comprises, successively from the transparent substrate 10 side, an alumina layer 11, a water barrier layer 12 having a refractive index lower than that of the alumina layer and serving a water barrier for the alumina layer 11, and a flattening layer 13 essentially comprising an alumina hydrate and having a refractive index lower than that of the water barrier layer 12, in which the thickness of the water barrier layer 12 is 70 nm or less.
