Chaotic Dirac billiard in graphene quantum dots
L. A. Ponomarenko, F. Schedin, M. I. Katsnelson +4
We report on transport characteristics of quantum dot devices etched entirely in graphene. At large sizes, they behave as conventional single-electron transistors, exhibiting perio…
Giant Intrinsic Carrier Mobilities in Graphene and Its Bilayer
S. V. Morozov, K. S. Novoselov, M. I. Katsnelson +4
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…
Making graphene visible
P. Blake, K. S. Novoselov, A. H. Castro Neto +5
Microfabrication of graphene devices used in many experimental studies currently relies on the fact that graphene crystallites can be visualized using optical microscopy if prepare…
Cyclotron Resonance study of the electron and hole velocity in graphene monolayers
R. S. Deacon, K-C. Chuang, R. J. Nicholas +2
We report studies of cyclotron resonance in monolayer graphene. Cyclotron resonance is detected using the photoconductive response of the sample for several different Landau level…
On the roughness of single- and bi-layer graphene membranes
J. C. Meyer, A. K. Geim, M. I. Katsnelson +5
We present a detailed transmission electron microscopy and electron diffraction study of the thinnest possible membrane, a single layer of carbon atoms suspended in vacuum and atta…
Room-Temperature Quantum Hall Effect in Graphene
K. S. Novoselov, Z. Jiang, Y. Zhang +7
The quantum Hall effect (QHE), one example of a quantum phenomenon that occur on a truly macroscopic scale, has been attracting intense interest since its discovery in 1980 and has…
