Abstract (EN): Using a semiclassical approach and input from experiments on the conductivity of graphene, we determine the electronic density dependence of the electronic transport coefficients-conductivity, thermal conductivity, and thermopower-of doped graphene. Also, the electronic density dependence of the optical conductivity is obtained. Finally, we show that the classical Hall effect (low field) in graphene has the same form as for the independent electron case, characterized by a parabolic dispersion, as long as the relaxation time is proportional to the momentum.
