Transport and elastic scattering times as probes of the nature of impurity scattering in single and bilayer graphene

M. Monteverde, C. Ojeda-Aristizabal, R. Weil +7

Both transport ${\tau }_{tr}$ and elastic scattering times ${\tau }_e$ are experimentally determined from the carrier density dependence of the magnetoconductance of monolayer and bilayer gr…
