Giant Phonon-induced Conductance in Scanning Tunneling Spectroscopy of Gate-tunable Graphene
Yuanbo Zhang, Victor W. Brar, Feng Wang +5
The honeycomb lattice of graphene is a unique two-dimensional (2D) system where the quantum mechanics of electrons is equivalent to that of relativistic Dirac fermions. Novel nanom…
Measurement of Scattering Rate and Minimum Conductivity in Graphene
Y. -W. Tan, Y. Zhang, K. Bolotin +6
The conductivity of graphene samples with various levels of disorder is investigated for a set of specimens with mobility in the range of cm/V sec. Comparing t…
Scanning tunneling spectroscopy of inhomogeneous electronic structure in monolayer and bilayer graphene on SiC
Victor W. Brar, Yuanbo Zhang, Yossi Yayon +6
We present a scanning tunneling spectroscopy (STS) study of the local electronic structure of single and bilayer graphene grown epitaxially on a SiC(0001) surface. Low voltage topo…
Energy Band Gap Engineering of Graphene Nanoribbons
Melinda Y. Han, Barbaros Oezyilmaz, Yuanbo Zhang +1
We investigate electronic transport in lithographically patterned graphene ribbon structures where the lateral confinement of charge carriers creates an energy gap near the charge…
Electric Field Effect Tuning of Electron-Phonon Coupling in Graphene
Jun Yan, Yuanbo Zhang, Philip Kim +1
Gate-modulated low-temperature Raman spectra reveal that the electric field effect (EFE), pervasive in contemporary electronics, has marked impacts on long wavelength optical phono…
Landau Level Splitting in Graphene in High Magnetic Fields
Y. Zhang, Z. Jiang, J. P. Small +7
The quantum Hall (QH) effect in two-dimensional (2D) electrons and holes in high quality graphene samples is studied in strong magnetic fields up to 45 T. QH plateaus at filling fa…
