High quality magnetotransport in graphene using the edge-free Corbino geometry
Y. Zeng, J. I. A. Li, S. A. Dietrich +5
We report fabrication of graphene devices in a Corbino geometry consisting of concentric circular electrodes with no physical edge connecting the inner and outer electrodes. High d…
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…
Regenerative oscillation and four-wave mixing in graphene optoelectronics
Tingyi Gu, Nick Petrone, James F. McMillian +6
The unique linear and massless band structure of graphene, in a purely two-dimensional Dirac fermionic structure, have led to intense research spanning from condensed matter physic…
Variable Electron-Phonon Coupling in Isolated Metallic Carbon Nanotubes Observed by Raman Scattering
Yang Wu, Janina Maultzsch, Ernst Knoesel +6
We report the existence of broad and weakly asymmetric features in the high-energy (G) Raman modes of freely suspended metallic carbon nanotubes of defined chiral index. A signific…
Single-Walled Carbon Nanotubes as Shadow Masks for Nanogap Fabrication
E. P. De Poortere, L. M. Huang, M. Huang +4
We describe a technique for fabricating nanometer-scale gaps in Pt wires on insulating substrates, using individual single-walled carbon nanotubes as shadow masks during metal depo…
