Presented here is a general analytical model for describing the energetics and relative stability of defective carbon SWNTs in the presence of adsorbates. The model is parameterized for the case of hydrogen, using results obtained from first principles simulations, and is constructed around experimentally relevant parameters such as the concentrations and configurations of adsorbates on the nanotube walls.7enAdsorbatesCarbon nanotubesTheory and modelingThermodynamics200610.1002/cvde.20050643133845580713
