In our density functional theory study we use the trimethylaluminum (TMA) atomic layer deposition (ALD) as a model process for a CNT-functionalization. Since this functionalization relies on the presence of OH-groups, the CNTs are exposed to a water or oxygen pre-treatment. We show that only CNTs with a single-vacancy defect are able to react with H$_{2}$O or O$_{2}$. Further, the defect is preferably saturated by oxygen.
