Intrinsic and extrinsic performance limits of graphene devices on SiO2.
TL;DR: It is shown that electron-acoustic phonon scattering is indeed independent of n, and contributes only 30 Omega to graphene's room-temperature resistivity, and its magnitude, temperature dependence and carrier-density dependence are consistent with extrinsic scattering by surface phonons at the SiO2 substrate.
Journal ArticleDOI
Atomic Structure of Graphene on SiO2
TL;DR: Atomic structures and nanoscale morphology of graphene-based electronic devices are revealed for the first time and a strong spatially dependent perturbation is revealed which breaks the hexagonal lattice symmetry of the graphitic lattice.
Journal ArticleDOI
Charged-impurity scattering in graphene
Jian-Hao Chen,Chaun Jang,Shaffique Adam,Michael S. Fuhrer,Ellen D. Williams,Masa Ishigami,Masa Ishigami +6 more
TL;DR: In this paper, a systematic study of the influence of scattering from impurities on the peculiar electronic properties of graphene is conducted by monitoring changes in electronic characteristics of initially clean graphene, by depositing potassium atoms onto its surface in ultrahigh vacuum.

Charged Impurity Scattering in Graphene
Journal ArticleDOI
Defect scattering in graphene.
TL;DR: Defected graphene shows a diverging resistivity at low temperature, indicating insulating behavior, and is best explained by ion-induced formation of lattice defects that result in midgap states.
