Aggregation of carbon nanotubes reduces quantum efficiency and the phenomenon is found to be related to photocurrent leakage through oxygenated lattices acting as low barrier intertube channels. This outcome is supported by calculation and optical excitation experiments.

When individual carbon nanotubes aggregate, the nanotube bundles behave as excellent thermal sensors and radiators. This is due to enhanced temperature dependent mechanism by internanotube junctions which act as thermal reservoirs.

A semiconducting phase is temporarily present in doped carbon nanotube after field treatment and underlying mechanism involves chemical potential change and EF movement by field induced charge accumulation. Metallic phase re-emerges as accumulated charges are released.
