We have studied the transport properties of graphene transistors in different solvents with
dielectric constant varying over 2 orders of magnitude. Upon increasing the dielectric …

The deposition effect of metals on graphene was studied by in situ field effect transistor
(FET) measurements in high vacuum. Metals such as gold (Au), silver (Ag), and copper (Cu) …

We calculate the classic Hall conductivity and mobility of the undoped and doped (or at the
gate voltage) graphene as a function of temperature, magnetic field, and carrier …

We report the study of graphene devices in Hall-bar geometry, gated with a polymer
electrolyte. High densities of 6× 10 13/cm 2 are consistently reached, significantly higher …

We report transport measurements through graphene on SrTiO 3 substrates as a function of
magnetic field B, carrier density n, and temperature T. The large dielectric constant of SrTiO …

The peculiar nature of electron scattering in graphene is among many exciting theoretical
predictions for the physical properties of this material. To investigate electron scattering …

We present a detailed study of the high-current transport properties of graphene devices
patterned in a four-point configuration. The current tends to saturate as the voltage across …

Electron transport in bilayer graphene placed under a perpendicular electric field is revealed
experimentally. Steep increase of the resistance is observed under high electric field; …

We demonstrate theoretically that most of the observed transport properties of graphene
sheets at zero magnetic field can be explained by scattering from charged impurities. We …
