We study the geometry-dependent resistivity scaling in single-walled carbon nanotube films as a function of nanotube and device parameters using Monte Carlo simulations. We first demonstrate that these simulations can model and fit recent experimental results on the scaling of nanotube film resistivity with device width. Furthermore, we systematically study the effect of four parameters; namely...

The use of carbon nanotubes for field effect nanoelectronic devices, which has been recently demonstrated, motivates further studies of electrochemical and chemical analogues of nanotube molecular transistors. However, chemical gating is not applicable for modern electronics due to its slow response. Herein we propose a novel molecular electronic device: Nanotube LightControlled Switch (NLCS). ...

We have developed a simple, convenient and inexpensive voltammetric method for determining trace Sudan I contamination in chili powder, based on the catalyzed electrochemical reduction of Sudan I at the carbon nanotube modified electrode. Under optimized conditions, the method exhibited acceptable analytical performance in terms of linearity (over the concentration range 6.0×10-7 to 7.5×10-5 M,...

We have investigated conditions for making nanoindents on a polycarbonate using a carbon nanotube tip in terms of structural stability of the nanotube tip. Even under a weak force of ∼ 50 nN acting in the axial direction to the nanotube, the indents with mean depth of 3.91 nm were successfully realized on the polycarbonate in air at room temperature. In this case, there were no structural chang...

Four-probe resistance vs temperature and gate voltage are reported for an individual single-wall carbon nanotube rope before and after doping in situ with potassium. All the features in R(T) from unoriented bulk material, before and after doping, are qualitatively reproduced by the rope data. The 5.3 K conductance of the pristine rope decreases with positive gate voltage, while G vs Vg becomes ...

Catalyst films undergo considerable surface morphology restructuring prior to carbon nanotube nucleation, deeply influencing the nanostructures obtained. Here we study the influence of different gaseous atmospheres on the structure of thin Fe films. The morphology is influenced by process temperature and substrate interactions and varying the gas type and pressure can control the average cataly...

We report a method to controllably alter the diameter of an individual carbon nanotube. The combination of defect formation via electron irradiation and simultaneous resistive heating and electromigration in vacuum causes the nanotube to continuously transform into a high-quality nanotube of successively smaller diameter, as observed by transmission electron microscopy. The process can be halte...
