    摘要： A three-dimensional graphene structure, and methods of manufacturing and transferring the same including forming at least one layer of graphene having a periodically repeated three-dimensional shape. The three-dimensional graphene structure is formed by forming a pattern having a three-dimensional shape on a surface of a substrate, and forming the three-dimensional graphene structure having the three-dimensional shape of the pattern by growing graphene on the substrate on which the pattern is formed. The three-dimensional graphene structure is transferred by injecting a gas between the three-dimensional graphene structure and the substrate, separating the three-dimensional graphene structure from the substrate by bonding the three-dimensional graphene structure to an adhesive support, combining the three-dimensional graphene structure with an insulating substrate, and removing the adhesive support.

    摘要： A photo-luminescent (PL) liquid crystal display (LCD) including a blue dichroic mirror layer disposed under a light emitting layer is provided. Visible light generated from the light emitting layer is mostly reflected to the front side of the PL LCD, thereby increasing the light utilization efficiency thereof. A blue PL quantum dot layer is formed in blue light regions, thereby improving a narrow viewing angle and an orientation in blue pixels. An ultraviolet (UV) filter blocking UV light in the ambient light is formed to protect the light emitting layer from the excitation caused by external light, thereby preventing degradation of contrast caused by an undesired light emission.

    摘要： A stack-type capacitor includes a lower electrode, a dielectric layer formed on the lower electrode, and an upper electrode formed on the dielectric layer, wherein the lower electrode includes a first metal layer having a cylindrical shape and a second metal layer filled in the first metal layer. In the capacitor, an amount of oxygen included in the lower electrode is decreased to suppress oxidation of a TiN layer. Thus, a stable stack-type capacitor may be formed, which increases greatly the performance of highly integrated DRAMs.
