Abstract: PURPOSE: A manufacturing method of high insulation aerogel impregnated fiber is provided to offer aerogel non-woven fabric/fiber of ambient drying type having low thermal conductivity, soundproof property and improved energy-saving efficiency. CONSTITUTION: The manufacturing method of high insulation aerogel impregnated fiber is as follows. Silica sol mixes alcoxysilane and isopropyl alcohol, and then proceeds hydrolysis by adding an acid solution to the mixed solution. A polymerization reaction of the silica sol is carried out by adding a small quantity of basic solution. The silica sol is impregnated in the fiber. The fiber is aged and solvent-substituted under a polar solvent. The aerogel impregnated fiber reforms the surface and proceeds the ambient drying process.

Abstract: A spin transistor using an epitaxial ferromagnetism-semiconductor junction is provided to reduce the length of a source and a drain by using the epitaxial ferromagnetic source and drain magnetized to a channel direction. A spin transistor includes a semiconductor substrate(110) having a channel layer(107). A ferromagnetism source(121) and a ferromagnetism drain are separately arranged in an upper part of the semiconductor substrate. The ferromagnetism source and drain are epitaxially grown on the semiconductor substrate. The ferromagnetism source and drain are magnetized to the longitudinal direction of the channel layer by the crystallization anisotropy. A gate(150) is arranged between the source and the drain in the upper part of the semiconductor substrate. The gate is insulated from the semiconductor substrate with the SiO2 gate insulating layer. The gate is formed in order to control the spin of the electron passing through the channel layer.
