Evolution of Landau Levels into Edge States at an Atomically Sharp Edge in Graphene
Guohong Li, Adina Luican, Dmitry Abanin +2
The quantum-Hall-effect (QHE) occurs in topologically-ordered states of two-dimensional (2d) electron-systems in which an insulating bulk-state coexists with protected 1d conductin…
Self-navigation of STM tip toward a micron sized sample
Guohong Li, Adina Luican, Eva Y. Andrei
We demonstrate a simple capacitive based method to quickly and efficiently locate micron size conductive samples on insulating substrates in a scanning tunneling microscope (STM).…
Quantized Landau level spectrum and its density dependence
Adina Luican, Guohong Li, Eva Y. Andrei
Scanning tunneling microscopy and spectroscopy in magnetic field was used to study Landau quantization in graphene and its dependence on charge carrier density. Measurements were c…
Single Layer Behavior and Its Breakdown in Twisted Graphene Layers
A. Luican, Guohong Li, A. Reina +5
We report high magnetic field scanning tunneling microscopy and Landau level spectroscopy of twisted graphene layers grown by chemical vapor deposition. For twist angles exceeding…
Observation of Van Hove singularities in twisted graphene layers
Guohong Li, A. Luican, J. M. B. Lopes dos Santos +4
Electronic instabilities at the crossing of the Fermi energy with a Van Hove singularity in the density of states often lead to new phases of matter such as superconductivity, magn…
Fractional quantum Hall effect and insulating phase of Dirac electrons in graphene
Xu Du, Ivan Skachko, Fabian Duerr +2
In graphene, which is an atomic layer of crystalline carbon, two of the distinguishing properties of the material are the charge carriers two-dimensional and relativistic character…
Integer and Fractional Quantum Hall Effect in Two-Terminal Measurements on Suspended Graphene
I. Skachko, X. Du, F. Duerr +4
We report the observation of the quantized Hall effect in suspended graphene probed with a two-terminal lead geometry. The failure of earlier Hall-bar measurements is discussed and…
Scanning Tunneling Spectroscopy of Graphene on Graphite
Guohong Li, Adina Luican, Eva Y. Andrei
We report low temperature high magnetic field scanning tunneling microscopy and spectroscopy of graphene flakes on graphite that exhibit the structural and electronic properties of…
