Figure 1. From: Flexible, transparent electrodes using carbon nanotubes.

Impedance dependence on frequency Z(f) for films of different SWCNT densities corresponding to different colors. The highest impedance corresponds to the lowest density. We can define the cutoff frequency (f0), at which Z decreases abruptly: f0 increases when increasing the SWCNT density on the substrate, while resistance decreases, as does the low-frequency impedance.

Figure 5. From: Flexible, transparent electrodes using carbon nanotubes.

Polarized-light Raman spectra recorded at two different perpendicular polarizations, XX and XY. The Raman G line spectra SXX and SXY correspond to the unstretched samples; EXX and EXY, to stretched samples with 10% elongation. One may observe how the intensity of the relationship after elongation, EXX/EXY ≈ 2.76, is increased respectively similar to that before elongation, SXX/SXY ≈ 2.03, which indicates a preferred orientation by stretching. Furthermore, the relation D/G remains unchanged, indicating that stretching does not appreciably introduce defects.
