Abstract:
A carbon nanotube(CNT) in which electronic is injected is provided to control easily doping of the carbon nanotube and electrical property such as band-gap etc. by diversifying treatment condition of reducing agent. A carbon nanotube(CNT) in which electronic is injected is generated using a reducing agent, and p-type doped CNT, neutral doped CNT, n-type doped CNT and a mixture thereof. An optical extinction rate of S11/S22 is 0.5 or greater. The reducing agent is a metal hydride, an organic reduction solvent or a hydrogen gas. The metal hydride is a borohydride system or an aluminum hydride. The organic reduction solvent is a hydrazine(N2H4), a glycol or a diol solvent.
Abstract:
A transparent electrode having a CNT(Carbon Nano Tube) and a method for manufacturing the transparent electrode are provided to improve electrical conductivity of the transparent electrode by increasing an amount of defects of the CNT. A transparent electrode includes a CNT, whose ID/IG value is greater than 0.25. The ID and IG are integration values on D and G bands, respectively, which are obtained by adopting a Raman spectroscopy. The ID/IG value of the CNT lies between 0.25 and 1.00. The CNT is a single-wall CNT, a thin multi-wall CNT, a multi-wall CNT, or a combination thereof. A mean length of the CNT lies between 0.1 and 500 mum. A solar cell includes a semiconductor electrode(10), an electrolyte layer(13), and a counter electrode(14).
Abstract:
PURPOSE: A carbon nanotube, a device containing the carbon nanotube, and a method for controlling the optical inter-band transition of the carbon nanotube are provided to improve the sensitivity and selectivity (purity) of a device. CONSTITUTION: A carbon nanotube is a p-doped carbon nanotube, wherein the carbon nanotube shows the optical inter-band transition in the VIS-NIR range, and only one optical inter-band transition appears at the corresponding p-doped state of the carbon nanotube. The carbon nanotube is p-doped by using an oxidant having a reduction potential of 0.8eV or more based on a standard hydrogen electrode. The carbon nanotube is p-doped by using an oxidant which is a metal salt or a nitronium compound.

Abstract:
PURPOSE: A method for producing carbon nano tube by injecting an electron into a nano tube which is doped with p-type is provided. CONSTITUTION: A method for producing CNT(carbon nano tube) composition in which an electron is injected comprises: a step of reacting the CNT with a reductant to obtain the CNT in which an electron with more than 1 of S11/S22 optical extinction ratio is injected; a step of centrifuging the CNT from the reacted mixture. The reductant is selected from metal hydride, organic reduction solvent or hydrogen gas.
