Carbon nanotube sheets have great potential for specific engineering applications owing to their unique, tunable properties such as conductivity. To date, most CNT sheet materials (e.g., buckypapers) are fabricated by using single wall carbon nanotubes (SWNTs). However, multi-wall carbon nanotubes (MWNTs) are much cheaper than SWNTs, and better suited to large scale industrial applications. One...

In recent years, the ternary boron carbonitride (BCN) nanotubes have attracted increasing interests because of their unique electronic properties and potential technological applications. A prime advantage of the BCN nanotubes over their carbon counterparts is the relative simplicity in manipulating the electronic structures. Theoretical calculations have predicted that the band gap of BCN nano...

Based on the transmission line model (TLM), we present an exact and general transfer function formula, useful for both single multiwall carbon nanotube (MWCNT) and MWCNT bundle interconnects. Using the standard parameters for 22-nm technology node we perform the Nyquist stability analysis, to investigate the dependence of the degree of relative stability for both single and bundle interconnects...

Low concentrations of multiwall carbon nanotubes MWCNTs 1 wt % uniformly distributed within the donor layer of a heterojunction organic solar cell are shown to be an effective means of greatly reducing cell series resistance without compromising cell shunt resistance, resulting in an increase in cell fill factor of 50–60%. By chemically functionalizing MWCNTs with polar surface moieties, it is ...

The interaction of H atoms with the curved concentric graphene walls of a multiwall carbon nanotube and the stacked planar graphene sheets of graphite was investigated using a combination of high resolution transmission electron microscopy HRTEM in conjunction with electron energy-loss and Raman spectroscopies. Continuous cylindrical graphene walls of a nanotube are etched and amorphized by the...
