摘要

奈米碳管(carbon nanotube, CNT)在1991年時意外在電弧放電法(arc-discharge method)中發現，因為奈米碳管的許多特性，讓科學家們在近20年內爭相討論，而對於改善燃料電池碳載體，以提昇其發電電效率的我們也不例外。
在翻閱了眾多論文與書籍後，發現目前化學沉積平台(chemical vapor deposition, CVD)是最簡易的成長方式，但不能在成長的同時控制其整體結構，為此，本文利用脈衝雷射沉積平台(pulsed-laser deposition, PLD)改善此缺點，脈衝雷射沉積平台不儘可以控制其成長位置，也能在成長的同時控制奈米碳管的結構。
目前尚未有人在脈衝雷射沉積平台中成長出奈米碳管，因此試著成長出奈米碳管成為本文的重點。本文將分為兩大目標做討論，第一是成長奈米碳管前所需要的催化劑，第二是利用此催化劑成長奈米碳管。

Carbon nanotube (CNT) was accidentally discovered in arc-discharge method in 1991. It is widely discussed by scientists in the last 20 years due to the unique characteristics of carbon nanotubes. Because of this unique characteristic, we believe that this is one solution to improve the electron efficiency of fuel cells.
Having done an in depth research in CNTs, chemical vapor disposition (CVD) is found to be the most common method to grow carbon nanotubes. However, it cannot control the structure of CNT during its growth. In our study, we have utilized pulsed-laser deposition (PLD) to overcome this disadvantage, as PLD can not only control the growth position, but also control the structure of CNT during its growth.
Theoretically, it is possible to grow CNT using PLD, therefore we are the first to adopt this technique in practice. The following are the two main objectives of this study: to firstly grow the catalyst required to grow CNT, and then utilize this catalyst in order to grow CNT.
