Study of Carbon Nanotube-Substrate Interaction

Figure 5

(a), (c), and (e) show spectroscopic images of G band of SWNT serpentines on quartz substrate, using the excitation laser wavelength of 532 nm ( 𝐸 l a s e r = 2 . 3 3  eV). (b), (d), and (f) show the G+ frequency of these SWNTs, observed in all points indicated by green pointers in (a), (c), and (e), respectively, plotted as a function of the distance 𝑠 , measured along the SWNT: (b) frequency has maximum and minimum following the tube-substrate morphology (a); (d) variation in frequency within experimental accuracy; (f) frequency “jumps” [55].
