Electronic Highways in Bilayer Graphene
Zhenhua Qiao, Jeil Jung, Qian Niu +1
Bilayer graphene with an interlayer potential difference has an energy gap and, when the potential difference varies spatially, topologically protected one-dimensional states local…
Universal Quenching of Superconductivity in Two-dimensional Nano-islands
Jungdae Kim, Gregory A. Fiete, Hyoungdo Nam +2
We systematically address superconductivity of Pb nano-islands with different thicknesses and lateral sizes via a scanning tunneling microscopy/spectroscopy. Reduction of the super…
Valley-Hall Kink and Edge States in Multilayer Graphene
Jeil Jung, Fan Zhang, Zhenhua Qiao +1
We report on a theoretical study of one-dimensional (1D) states localized at few-layer graphene system ribbon edges, and at interfaces between few-layer graphene systems with diffe…
Drude weight, plasmon dispersion, and a.c. conductivity in doped graphene sheets
Saeed H. Abedinpour, G. Vignale, A. Principi +3
We demonstrate that the plasmon frequency and Drude weight of the electron liquid in a doped graphene sheet are strongly renormalized by electron-electron interactions even in the…
Landau Levels and Band Bending in Few-Layer Epitaxial Graphene
Hongki Min, S. Adam, Young Jae Song +3
The carrier density distributions in few-layer-graphene systems grown on the carbon face of silicon carbide can be altered by the presence of a scanning tunneling microscope (STM)…
