Abstract:
Disclosed are a method of transferring graphene and a method of manufacturing a device using the same. The method of transferring graphene includes the steps of: forming a graphene layer on a substrate containing a base metal catalyst (for example, a semiconductor catalyst); forming a thin film on the graphene layer; and separating a lamination structure of the graphene layer and the thin film from the substrate. The base metal catalyst (for example, a semiconductor catalyst) may contain at least one among Ge and SiGe. The thin film may include an inorganic thin film and may have a single layered structure or a multi-layered structure. The step of separating a lamination structure from a substrate may be performed by a physical detachment process. After the step of separating the lamination structure from the substrate, a step of forming an organic film on the substrate may be further performed.
Abstract:
Provided are a nanowire-graphene structure, a device including the same, and a manufacturing method thereof. The manufacturing method for a nanowire-graphene structure of the present invention includes: a step of growing a graphene layer on a substrate; a step of growing a plurality of nanowires on the graphene layer; and a step of separating the graphene layer from the substrate, wherein the substrate is made of a material which does not form a covalent bond with the graphene layer.

Abstract:
PURPOSE: A porous nanostructure and a producing method thereof are provided to remarkably increase the surface area of the nanostructure by producing pores on the surface and the inside of the nanostructure. CONSTITUTION: A porous nanostructure includes pores(12) formed on the surface and the inside of the nanostructure(10). The pores are through-holes. The nanostructure is either a nanotube or a nanowire. The nanostructure contains a p-type or an n-type dopant. A producing method of the nanostructure comprises the following steps: attaching nanoparticles on the surface of the nanostructure; oxidizing the nanostructure for forming oxides on the surface of the nanostructure; and removing the oxides and the nanoparticles from the nanostructure.
