Specific features of electric charge screening in few-layer graphene films.
We present a nonlinear Thomas-Fermi theory which describes the electric charge screening in a system including two charged substrate layers separated by a few-layered graphene film. We show that by increasing the charge at the interfaces, the system can be turned from the weak screening regime where the whole film responds to the external charge to the strong screening regime where the external...
متن کاملCharge carriers in few-layer graphene films.
The nature of the charge carriers in 2D few-layer graphites (FLGs) has been recently questioned by transport measurements [K. S. Novoselov, Science 306, 666 (2004)10.1126/science.1102896] and a strong ambipolar electric field effect has been revealed. Our density functional calculations demonstrate that the electronic band dispersion near the Fermi level, and consequently the nature of the char...
متن کاملSymmetry Breaking in Few Layer Graphene Films
Recently, it was demonstrated that the quasiparticle dynamics, the layer-dependent charge and potential, and the c-axis screening coefficient could be extracted from measurements of the spectral function of few layer graphene films grown epitaxially on SiC using angle-resolved photoemission spectroscopy (ARPES). In this article we review these findings, and present detailed methodology for extr...
متن کاملWeak localization in electric-double-layer gated few-layer graphene
We induce surface carrier densities up to ∼ ⋅ 7 1014 cm−2 in few-layer graphene devices by electric double layer gating with a polymeric electrolyte. In 3-, 4and 5-layer graphene below 20–30 K we observe a logarithmic upturn of resistance that we attribute to weak localization in the diffusive regime. By studying this effect as a function of carrier density and with ab initio calculations we de...
متن کاملCharge-carrier screening in single-layer graphene.
The effect of charge-carrier screening on the transport properties of a neutral graphene sheet is studied by directly probing its electronic structure. We find that the Fermi velocity, Dirac point velocity, and overall distortion of the Dirac cone are renormalized due to the screening of the electron-electron interaction in an unusual way. We also observe an increase of the electron mean free p...
