Abstract
In this work, we have studied the resonance Raman spectra of 17
single-wall carbon nanotube (SWNT) serpentines, using a 532 nm laser.
Each serpentine consists of a series of straight, parallel, and
regularly spaced segments, connected by alternating U-turns formed on
top of crystalline miscut quartz. The interaction between the SWNT and
the substrate affects the properties of nanotubes, generating different
behaviors of the G-band. We observed variations in the G-band frequency
along the SWNTs, which can be organized into three different groups, as
a result of different types of interaction with the substrate, generated
during the deposition of the SWNTs. (C) 2011 WILEY-VCH Verlag GmbH &
