We have studied temperature dependences of electron transport in graphene and its bilayer and found extremely low electron-phonon scattering rates that set the fundamental limit on possible charge carrier mobilities at room temperature. Our measurements show that mobilities higher than 200 000 cm2/V s are achievable, if extrinsic disorder is eliminated. A sharp (thresholdlike) increase in resistivity observed above approximately 200 K is unexpected but can qualitatively be understood within a… Expand

Recent studies have shown that a high K dielectric solvent screens the impurities for room temperature transport in graphene and the mobility has been found to increase by orders of magnitude. ThisExpand
Low bias short channel impurity mobility in graphene from first principles
In theory, graphene should exhibit very high carrier mobility, however its measured mobility is usually much lower. This discrepancy between theory and empirical observations is believed to be due toExpand
Correlated charged impurity scattering in graphene.
Impurity correlations offer a self-consistent explanation to the puzzling sublinear carrier-density dependence of conductivity commonly observed in monolayer graphene samples on substrates. Expand
Temperature-dependent resistivity in bilayer graphene due to flexural phonons
We have studied electron scattering by out-of-plane (flexural) phonons in doped suspended bilayer graphene. We have found the bilayer membrane to follow the qualitative behavior of the monolayerExpand

ABSTRACT We propose an approach that allows us to take into account the location of atomic defects in the graphene structure and describe the effect of electron scattering on certain configurationsExpand
Ultrahigh electron mobility in suspended graphene
Abstract We have achieved mobilities in excess of 200,000 cm2 V −1 s−1 at electron densities of ∼2 ×1011 cm−2 by suspending single layer graphene. Suspension ∼150 nm above a Si/SiO2 gate electrodeExpand
Mobility in semiconducting graphene nanoribbons: Phonon, impurity, and edge roughness scattering
The transport properties of carriers in semiconducting graphene nanoribbons are studied by comparing the effects of phonon, impurity, and line-edge roughness scattering. It is found that scatteringExpand
Anomalous Spectral Features of a Neutral Bilayer Graphene
By studying undoped exfoliated bilayer graphene with ARPES, two essential aspects of its many-body physics are revealed: the electron-phonon scattering rate has an anisotropic k-dependence and the type of electronic liquid is non-Fermi liquid. Expand
Effect of magnetic field on the electronic transport in trilayer graphene.
The results reveal that the energy gap in the trilayer graphene is thermally activated and increases with √B, which is a strong function of temperature. Expand
