Correlated Charged Impurity Scattering in Graphene
Correlated Charged Impurity Scattering in Graphene
We study electron transport properties of graphene in the presence of correlated charged impurities via adsorption and thermal annealing of potassium atoms. For the same density of charged scattering centers, the sample mobility sensitively depends on temperature which sets the correlation length between the scatterers. The data are well-understood by …
