  We present first-principles quantum transport simulations of single-walled
carbon nanotubes based on the NEGF method and including carrier-carrier
interactions within the self-consistent GW approximation. Motivated by the
characteristic enhancement of interaction between charge carriers in
one-dimensional systems, we show that the developed framework can predict Auger
recombination, hot carrier relaxation, and impact ionization in this type of
nanostructures. Using the computed scattering rates, we infer the inverse
electron-hole pair lifetimes for different Auger processes in several device
configurations.
