Abstract: Provided is a method for preparing a one-dimensional spin photonic crystal device and a one-dimensional spin photonic crystal device prepared by the same. The method comprises forming magnetic and nonmagnetic regions by the interference of laser beams generated from a femtosecond laser light source. The method of the present invention enables production of one-dimensional spin photonic crystals having excellent properties by a rapid and simple process, and is therefore suitable for high integration and large-scale production of desired devices. Further, the prepared photonic crystals exhibit excellent magneto-optical effects and are therefore applicable to development of novel optical devices, and the like.

Abstract: A method for fabricating a semiconductor device includes forming a gate structure comprising a stacked structure of a gate electrode and a gate hard mask layer over a semiconductor substrate having a device isolation structure. An insulating film filling up the gate structure is formed. A predetermined region of the insulating film is selectively etched to expose the semiconductor substrate of a bit line contact region. A C-HALO ion implantation process is subjected to the exposed semiconductor substrate. The insulating film is removed.

Abstract: A nitrogen selective adsorbent comprises a zeolite of a faujasite crystalline structure containing Li+ and at least one of NH+ and H+ as essential cations, and has a nitrogen adsorption characteristic represented by specific correlation between the number of associated Li+ ions per unit lattice of a zeolite crystal and the amount of adsorbed nitrogen per unit lattice of the zeolite crystal. An air separation method employs the aforesaid nitrogen selective adsorbent for separation between nitrogen and oxygen by selective adsorption of nitrogen in air.

Abstract: A nitrogen adsorbent comprising a crystalline X zeolite having a faujasite structure with an SiO2/Al2O3 ratio of less than 3.0, wherein the crystal contains at least one trivalent element of the group consisting of Fe, B and Ga and (AlO4)5− tetrahedral units thereof associated with cations. Although the adsorbent contains a designated trivalent element in the zeolite, it maintains the number of cation sites contributing to adsorption, has an excellent separation performance of nitrogen and oxygen, and exhibits excellent heat resistance. Further, when the nitrogen adsorbent of the present invention is used in such a particular manner that it adsorbs nitrogen after being heated under a vacuum, adsorption performance is improved.
