    • Disclosed are: Au—Ag core-shell nanorod particles wherein a cationic surfactant such as CTAB is substituted by an other compound; and a method for producing the Au—Ag core-shell nanorod particles. Specifically disclosed are Au—Ag core-shell nanorod particles which are characterized in that each of the nanorod particles comprises a gold nanorod particle that serves as the core, a shell layer that covers the surface of the gold nanorod particle and is formed from silver, and a copolymer that adsorbs on the surface of the shell layer. The Au—Ag core-shell nanorod particles are also characterized in that the copolymer is a block copolymer or graft copolymer that is obtained by polymerizing at least a polymerizable monomer (A) that has a group represented by general formula (I). In the formula, Ra represents an alkylene group having 2-7 carbon atoms.

    • A semiconductor device has a satisfactory ohmic contact on a p-type principal surface tilting from a c-plane. The principal surface 13a of a p-type semiconductor region 13 extends along a plane tilting from a c-axis (axis ) of hexagonal group-III nitride. A metal layer 15 is deposited on the principal surface 13a of the p-type semiconductor region 13. The metal layer 15 and the p-type semiconductor region 13 are separated by an interface 17 such that the metal layer functions as a non-alloy electrode. Since the hexagonal group-III nitride contains gallium as a group-III element, the principal surface 13a comprising the hexagonal group-III nitride is more susceptible to oxidation compared to the c-plane of the hexagonal group-III nitride. The interface 17 avoids an increase in amount of oxide after the formation of the metal layer 15 for the electrode.
    • 半导体器件在从c面倾斜的p型主表面上具有令人满意的欧姆接触。 p型半导体区域13的主表面13a沿着从六方晶III族氮化物的c轴(轴<0001>)倾斜的平面延伸。 金属层15沉积在p型半导体区域13的主表面13a上。金属层15和p型半导体区域13被界面17分离,使得金属层用作非合金电极 。 由于六方晶III族氮化物含有镓作为III族元素,所以与六方晶III族氮化物的c面相比,包含六方晶III族氮化物的主表面13a更易于氧化。 界面17避免了形成用于电极的金属层15之后的氧化物的量的增加。

    • A retinal scanning image display apparatus includes a light source, a scanning unit that scans a light flux from the light source, a reflective surface that reflects the light flux from the scanning unit, and an ocular unit that guides the light flux from the reflective surface to an eye of an observer. Optical paths of the light flux scanned by the scanning unit intersect at an exit pupil position of the ocular unit, and the image display apparatus causes the scanning unit and the reflective surface to shift so that the optical paths of the scanned light flux toward the same image position are respectively moved in parallel to move the intersecting position of those optical paths. This realizes a small retinal scanning image display apparatus capable of keeping the image position substantially constant even when an observer moves their pupil.
    • 视网膜扫描图像显示装置包括光源,扫描来自光源的光束的扫描单元,反射来自扫描单元的光束的反射表面和从反射表面引导光束的眼单元 到观察者的眼睛。 由扫描单元扫描的光束的光路在眼单元的出射光瞳位置相交,图像显示装置使扫描单元和反射面移动,使得扫描光的光路朝向相同 图像位置分别平行移动以移动那些光路的相交位置。 这实现了即使当观察者移动其瞳孔时也能够使图像位置保持基本恒定的小型视网膜扫描图像显示装置。
