• 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
