Ballistic carbon nanotube field-effect transistors
It is shown that contacting semiconducting single-walled nanotubes by palladium, a noble metal with high work function and good wetting interactions with nanotube, greatly reduces or eliminates the barriers for transport through the valence band of nanot tubes. Expand
Chemically Derived, Ultrasmooth Graphene Nanoribbon Semiconductors
We developed a chemical route to produce graphene nanoribbons (GNR) with width below 10 nanometers, as well as single ribbons with varying widths along their lengths or containing lattice-definedExpand
Thermal conductance of an individual single-wall carbon nanotube above room temperature.
This work discusses sources of uncertainty and proposes a simple analytical model for the SWNT thermal conductivity including length and temperature dependence, which is attributed to second-order three-phonon scattering between two acoustic modes and one optical mode. Expand
PEGylated nanographene oxide for delivery of water-insoluble cancer drugs.
The results showed that graphene is a novel class of material promising for biological applications including future in vivo cancer treatment with various aromatic, low-solubility drugs. Expand

Carbon nanotubes are graphene sheets rolled-up into cylinders with diameters as small as one nanometer. Extensive work carried out worldwide in recent years has revealed the intriguing electrical andExpand
Nano-graphene oxide for cellular imaging and drug delivery
It is found that simple physisorption via π-stacking can be used for loading doxorubicin, a widely used cancer drug onto NGO functionalized with antibody for selective killing of cancer cells in vitro. Expand
Crystalline Ropes of Metallic Carbon Nanotubes
X-ray diffraction and electron microscopy showed that fullerene single-wall nanotubes (SWNTs) are nearly uniform in diameter and that they self-organize into “ropes,” which consist of 100 to 500 SWNTs in a two-dimensional triangular lattice with a lattice constant of 17 angstroms. Expand
Self-Aligned Ballistic Molecular Transistors and Electrically Parallel Nanotube Arrays
Carbon nanotube field-effect transistors with structures and properties near the scaling limit with short (down to 50 nm) channels, self-aligned geometries, palladium electrodes with low contactExpand
Electrical and thermal transport in metallic single-wall carbon nanotubes on insulating substrates
We analyze transport in metallic single-wall carbon nanotubes (SWCNTs) on insulating substrates over the bias range up to electrical breakdown in air. To account for Joule self-heating, aExpand
Noncovalent functionalization of carbon nanotubes for highly specific electronic biosensors
An exploration of single-walled carbon nanotubes is presented as a platform for investigating surface–protein and protein–protein binding and developing highly specific electronic biomolecule detectors for detecting clinically important biomolecules such as antibodies associated with human autoimmune diseases.
