We have been studying the heat conduction along a single-walled carbon nanotube (SWNT) by the molecular dynamics method [1-3] with the simplified form [4] of Tersoff-Brenner bond order potential [5]. Our preliminary results showed that thermal conductivity was strongly dependent on the nanotube length for realistic length scale for device applications [2, 3]. Furthermore, we have reported the d...

With unique hierarchical fibrillar structures on their feet, gecko lizards can walk on vertical walls or even ceilings. Recent experiments have shown that strong binding along the shear direction and easy lifting in the normal direction can be achieved by forming unidirectional carbon nanotube array with laterally distributed tips similar to gecko's feet. In this study, a multiscale modeling ap...

Magnetic iron oxide nanoparticles and near-infrared (NIR) fluorescent single-walled carbon nanotubes (SWNT) form heterostructured complexes that can be utilized as multimodal bioimaging agents. Fe catalyst-grown SWNT were individually dispersed in aqueous solution via encapsulation by oligonucleotides with the sequence d(GT)15, and enriched using a 0.5 T magnetic array. The resulting nanotube c...

A novel vertically aligned carbon nanotube based electrical cell impedance sensing biosensor (CNT-ECIS) was demonstrated for the first time as a more rapid, sensitive and specific device for the detection of cancer cells. This biosensor is based on the fast entrapment of cancer cells on vertically aligned carbon nanotube arrays and leads to mechanical and electrical interactions between CNT tip...

It seems likely that density concerns will force the DRAM community to consider using radically different schemes for Ihe implementation of memory devices. We propose using nano-scale carbon structures as the basis for a memory device. A single-wall carbon nanotube would contain a charged buckyball. That buckyball wiLL stick tightly to one end of the tube or the other. We assign the bit value o...

Drift–diffusion model is applied for transport in a one–dimensional field effect transistor. A unified description is given for a semiconductor nanowire and a long single–wall nanotube basing on a self–consistent electrostatic calculations. General analytic expressions are found for basic device characteristic which differ from those for bulk transistors. We explain the difference in terms of w...

We demonstrate experimentally that noncollinear intrinsic spin-orbit magnetic fields can be realized in a curved carbon nanotube two-segment device. Each segment, analyzed in the quantum dot regime, shows near fourfold degenerate shell structure allowing for identification of the spin-orbit coupling and the angle between the two segments. Furthermore, we determine the four unique spin direction...

A novel immobilized fullerene–single wall carbon nanotube (C60–SWCNT) complex was synthesized via a microwave induced functionalization approach. It has been used as a component of the photoactive layer in a bulk heterojunction photovoltaic cell. As compared to a control device with only C60, the addition of SWCNTs resulted in an improvement of both the short circuit current density JSC and the...
