Direct mechanical measurement of the tensile strength and elastic modulus of multiwalled carbon nanotubes
Abstract We have conducted pulling and bending tests on individual carbon nanotubes in-situ in a transition electron microscope. Based on our observation of the force required to break the tube, aExpand
Direct observation of a widely tunable bandgap in bilayer graphene
This work demonstrates a gate-controlled, continuously tunable bandgap of up to 250 meV and suggests novel nanoelectronic and nanophotonic device applications based on graphene that have eluded previous attempts. Expand
Graphene plasmonics for tunable terahertz metamaterials.
It is demonstrated that graphene plasmon resonances can be tuned over a broad terahertz frequency range by changing micro-ribbon width and in situ electrostatic doping and the results represent a first look at light-plasmon coupling in graphene and point to potential graphene-based terAhertz metamaterials.

Boron Nitride Nanotubes
Electron energy-loss spectroscopy on individual tubes yielded B:N ratios of approximately 1, which is consistent with theoretical predictions of stable BN tube structures. Expand
Measurement of the Elastic Modulus of a Multi-Wall Boron Nitride Nanotube
We have experimentally determined the elastic properties of an individual multi-wall boron nitride (BN) nanotube. From the thermal vibration amplitude of a cantilevered BN nanotube observed in aExpand
Origin of spatial charge inhomogeneity in graphene
In an ideal graphene sheet, charge carriers behave as two-dimensional Dirac fermions 1 . This has been confirmed by the discovery of a half-integer quantum Hall effect in graphene flakes placed on aExpand
Graphene at the Edge: Stability and Dynamics
This study of an ideal low-dimensional interface, a hole in graphene, exhibits the complex behavior of atoms at a boundary with the mechanism of edge reconstruction investigated and the stability of the “zigzag” edge configuration demonstrated. Expand
We have measured the temperature-dependent thermal conductivity {kappa}(T) of crystalline ropes of single-walled carbon nanotubes from 350 K to 8 K. {kappa}(T) decreases smoothly with decreasingExpand
Direct imaging of lattice atoms and topological defects in graphene membranes.
Multiple five- and seven-membered rings appear exclusively in combinations that avoid dislocations and disclinations, in contrast to previous observations on highly curved (tube- or fullerene-like) graphene surfaces. Expand
Nanotube radio.
A fully functional, fully integrated radio receiver from a single carbon nanotube, which serves simultaneously as all essential components of a radio: antenna, tunable band-pass filter, amplifier, and demodulator. Expand
