Landau Levels of Topologically-Protected Surface States Probed by Dual-Gated Quantum Capacitance
Su Kong Chong, Ryuichi Tsuchikawa, Jared Harmer +2
Spectroscopy of discrete Landau levels (LLs) in bulk-insulating three-dimensional topological insulators (3D TIs) in perpendicular magnetic field characterizes the Dirac nature of…
Topological Insulator-Based van der Waals Heterostructures for Effective Control of Massless and Massive Dirac Fermions
Su Kong Chong, Kyu Bum Han, Akira Nagaoka +8
Three dimensional (3D) topological insulators (TIs) are an important class of materials with applications in electronics, spintronics and quantum computing. With the recent develop…
Scattering strength of potassium on a carbon nanotube with known chirality
Ryuichi Tschikawa, Daniel Heligman, Z. Y. Zhang +4
We have measured the scattering strength of charged impurities on a semiconducting single-walled carbon nanotube with known chirality. The resistivity of the nanotube is measured a…
Effects of Layer Stacking on the Combination Raman modes in Graphene
Rahul Rao, Ramakrishna Podila, Ryuichi Tsuchikawa +4
We have observed new combination modes in the range from 1650 - 2300 cm-1 in single-(SLG), bi-, few-layer and incommensurate bilayer graphene (IBLG) on silicon dioxide substrates.…
Uncovering the Dominant Scatterer in Graphene Sheets on SiO2
Jyoti Katoch, J. H. Chen, Ryuichi Tsuchikawa +3
We have measured the impact of atomic hydrogen adsorption on the electronic transport properties of graphene sheets as a function of hydrogen coverage and initial, pre-hydrogenatio…
