摘要：
We report preliminary results on studying the radiation stability of carbon nanotubes (CNs). Three different combinations of radiation and in situ characterization are used. Experiments include 30 keV electron bombardment with in situ characterization using a scanning electron microscope (SEM), 30 keV Ga ion bombardment with in situ SEM characterization, and 2 MeV proton irradiation with in situ electric resistance measurements. The study shows the degradation of CNs with dimensional shrinkage upon radiation, and the existence of a quasi steady state of defect creation and annealing.
