Carbon Nanotubes as a Capacitor: Theory and Expectation of a New Method

Heonjoo Ha

The aim of this project is to come up with a new method of using Carbon Nanotubes(CNTs) as a novel capacitor. In order to do this, we will use various methods to improve the electrical properties of the CNTs, and use it as a highly electric-energy-dense capacitor. After coating CNTs with an appropriate conducting polymer, we will attach the material with metals which contains abundant amount of free electrons. By attaching the final products in series, it is expected to perform high voltages suitable for nano-size devices. In this presentation, we are going to present the main idea by using various figures and diagrams, which was obtained by the aid of MATLAB. Also demonstrate the expected probability of free electrons charged in CNTs, by observing the difference occurred while adjusting the Fermi levels and the thickness of conducting polymer.
