Journal ArticleDOI
Electric field effect tuning of electron-phonon coupling in graphene.
TL;DR: Gate-modulated low-temperature Raman spectra reveal that the electric field effect (EFE), pervasive in contemporary electronics, has marked impacts on long-wavelength optical phonons of graphene and demonstrate optically the particle-hole symmetry about the charge-neutral Dirac point.
Journal ArticleDOI
Visualizing individual nitrogen dopants in monolayer graphene.
Liuyan Zhao,Rui He,Kwang Taeg Rim,Theanne Schiros,Keun Soo Kim,Keun Soo Kim,Hui Zhou,Christopher Gutierrez,Sreekumar Chockalingam,C. Arguello,Lucia Palova,Dennis Nordlund,Mark S. Hybertsen,David R. Reichman,Tony F. Heinz,Philip Kim,Aron Pinczuk,George W. Flynn,Abhay Pasupathy +18 more
TL;DR: Findings show that chemical doping is a promising route to achieving high-quality graphene films with a large carrier concentration.
Journal ArticleDOI
Two-Dimensional Mott-Hubbard Electrons in an Artificial Honeycomb Lattice
Achintya Singha,Marco Gibertini,Biswajit Karmakar,Shengjun Yuan,Marco Polini,Giovanni Vignale,Giovanni Vignale,Mikhail I. Katsnelson,Aron Pinczuk,Loren Pfeiffer,Ken W. West,Vittorio Pellegrini +11 more
TL;DR: The excitation spectrum in a magnetic field is probed, identifying collective modes that emerged from the Coulomb interaction in the artificial lattice, as predicted by the Mott-Hubbard model and suggesting the existence of a Coulomb-driven ground state.
Journal ArticleDOI
Engineering artificial graphene in a two-dimensional electron gas
Marco Gibertini,Achintya Singha,Vittorio Pellegrini,Marco Polini,Giovanni Vignale,Aron Pinczuk,Loren Pfeiffer,Ken W. West +7 more
TL;DR: In this paper, the authors show that modulating a two-dimensional electron gas with a long-wavelength periodic potential with honeycomb symmetry can lead to the creation of isolated massless Dirac points with tunable Fermi velocity.
Journal ArticleDOI
Observation of anomalous phonon softening in bilayer graphene.
TL;DR: The observation in bilayer graphene of an unusual phonon softening that provides the first experimental proof for another type of phonon anomaly is reported, which is a logarithmic singularity in the phonon group velocity.
