Investigation of Chirality Selection Mechanism of Single Walled Carbon Nanotube-3

Abstract

In this project final report, the PI described a new method to improve carbon nanotube (CNT) array growth by the rational design of the catalyst layer. The PI adapted Fe ion implantation as a new catalyst deposition method. The PI tested the performance of Fe-implanted wafer as catalyst for CNT forest growth and, unlike catalysts formed from PVD method, it was confirmed that the catalysts formed on Fe implanted wafer maintain their size and number density even after prolonged growth duration. As a result, the Fe-implanted wafer is effective in (1) growth of CNT forests having uniform diameter distribution and (2) growth of tall CNT forests by maintaining the number density of catalysts during the growth. The PI also has 1 peer reviewed paper as a result of the grant titled: Synthesis of CNT forest with narrow diameter distribution from the Fe ion implanted wafer, Carbon, vol. 123, pp. 122-128 (2017).
