Abstract

We report pump-probe transient absorption spectroscopy on carbon nanotubes with a high initial excitation density. We find that the recovery of the ground state optical absorption is well described by a $1 ∕ \sqrt{t}$ relaxation, indicating that the long time population relaxation is controlled by one-dimensional diffusion limited two body recombination.
