Query: Modeling charge relaxation in graphene quantum dots induced by
  electron-phonon interaction   We study and compare two analytic models of graphene quantum dots for
calculating charge relaxation times due to electron-phonon interaction.
Recently, charge relaxation processes in graphene quantum dots have been probed
experimentally and here we provide a theoretical estimate of relaxations times.
By comparing a model with pure edge confinement to a model with electrostatic
confinement, we find that the latter features much larger relaxation times.
Interestingly, relaxation times in electrostatically defined quantum dots are
predicted to exceed the experimentally observed lower bound of ~100 ns.
