Electrical transport measurements of the side-contacts and embedded-end-contacts of platinum leads on the same single-walled carbon nanotube

Abstract

In this work, we made both side-contact and embedded-end-contact Pt leads on the same individual carbon nanotube (CNT). The radial breathing mode (RBM) peak in the Raman spectrum showed that the nanotube was a single-walled carbon nanotube (SWCNT) of 1.5 nm in diameter. The electrical transport measurements showed that there was no observable difference in the I-V characteristics between side-contacts and embedded-end-contacts. Our experimental result confirmed a recent theoretical prediction. © 2009 IOP Publishing Ltd.
