Accumulation and recovery of radiation-induced damages in single-walled carbon nanotube bundles

In presented study we investigate the influence of electron irradiation, with energy of incident electrons 1 MeV, on the electrical resistance of single-walled carbon nanotube bundles. Irradiation was performed at liquid helium temperature for the first time. To determine radiationinduced damages accumulation and its further thermal recovering, the samples resistance was in situ measured in wide temperature range (5 – 300 K). The results reveal radiation damage annealing at temperature ~ 200 K that we associate with formation of inter-tube links in the bundles.
