• is sensitive to potential drops in the entire sample, the measurements give insights into charge-carrier transport processes of the particle network. Figure 7 shows the time evolution of the measured CPD values after the turning on and off of the laser light illumination with a wavelength of 408 nm

• induce cross linking between the inner shells (walls) of the tubes through sp3 bond formation, facilitating charge-carrier hopping to inner shells [28]. Such intershell bridging provides additional charge-carrier transport pathways, offsetting the effect of a conductivity decrease induced by defect
