Motivated by recent experiments by Yuri M. Zuev et al. [Phys. Rev. Lett. 102, 096807 (2009)], Peng Wei et al. [Phys. Rev. Lett. 102, 166808 (2009)], and Joseph G. Checkelsky et al. [Phys. Rev. B 80, 081413(R) (2009)], we calculate the thermopower of graphene incorporating the energy dependence of various transport scattering times. We find that scattering by screened charged impurities gives a reasonable explanation for the measured thermopower. The calculated thermopower behaves as \$1/\sqrt{n…
