Disclosed are a carbon nano-tube (CNT) light emitting device and a method of manufacturing the same. Specifically, the CNT light emitting device comprises: a CNT thin film formed using a CNT dispersed solution; a n-doping polymer formed on one end of the CNT thin film; a p-doping polymer formed on the other end of the CNT thin film; and a light emitting part between the n-doping polymer and the p-doping polymer. In addition, the method of manufacturing a CNT light emitting device comprises steps of: mixing CNTs with a dispersing agent or dispersing solvent to prepare a CNT dispersed solution; forming a CNT thin film using the CNT dispersed solution; coating a n-doping polymer on one end of the CNT thin film; and coating a p-doping polymer on the other end of the CNT thin film. According to the invention, the n-doping polymer and the p-doping polymer are respectively coated on the CNT having a CNT random network structure to implement a p-n junction, thereby implementing a light emitting device in a simple and low-priced process.
Abstract:
A method of fabricating a liquid film is provided. The method comprises the steps of applying hydrophilic liquid onto a substrate with an electrode formed thereunder, covering the hydrophilic liquid with a protection film comprising hydrophobic liquid, dispersing surfactant for reducing the surface tension between the hydrophilic liquid and the protection film, and applying voltage to the hydrophilic liquid and the electrode to wet the substrate with the hydrophilic liquid. With the surfactant and the electro-wetting principle, a contact angle between the hydrophilic liquid and the substrate is controlled. The liquid film having a uniform thickness in nano size is thus formed on the substrate. The protection film prevents the evaporation of the liquid film in the air to thereby secure the stability of the liquid film.

Abstract:
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.

A method for scheduling packets from a plurality of radio bearers by a scheduler of a first layer includes calculating a virtual scheduling time for the radio bearers by using a packet delay variation of the radio bearers, and transmitting the packet of the radio bearer having the greatest virtual scheduling time from among the plurality of radio bearers to a second layer.
Abstract:
A carbonization catalyst for forming graphene may be exfoliated from a graphene sheet by etching. A binder layer may be formed on the graphene sheet on which a carbonization catalyst is formed, to support and fix all or part of the graphene sheet. Further, the graphene sheet from which the carbonization catalyst is exfoliated may be transferred to a device. When exfoliating the carbonization catalyst from the graphene sheet, an acid may be used together with a wetting agent.
Abstract:
A heat transfer medium and a heat transfer method using the same are provided. The heat transfer medium comprises a film coated with a plurality of nano particles, which absorb light incident to the film to thereby transfer heat to a target object. When nano particles are applied onto a target object, the particles are removed by etching, and when a transparent film coated thereon with the nano particles is positioned, as a mask, on a target object requiring heat transfer, and then is exposed to infrared rays, heat is transferred to a specified portion of a target object under the coated nano particles, thereby obtaining a heat transfer effect without leaving unnecessary heat generating materials.
