High density, large-area single-walled carbon nanotube networks on nanoscale patterned substrates

Article Abstract:

A further enhanced method to build high yielded growth of single walled carbon nanotube (SWNT) architectures forming fully bridged networks between patterned structures by controlling CVD parameters and catalyst deposition and selecting optimal substrate materials is presented. The conclusion states that the method provides a very simple and effective way to build highly dense self assembled SWNT network on nanostructure substrates.

Preparation of I2@SWNTs: Synthesis and spectroscopic characterization of I2-loaded SWNTs

Article Abstract:

X-ray photoelectron spectroscopy (XPS), inducively coupled plasma analysis (ICP-AE) and Raman spectroscopy were used to define the location and to quantify the amount of iodine in HiPco SWNT sample loaded with molecular I2 through sublimation. The 12 SWNT contain ~25wt% of I2 and are stable without the loss of v even after exposure to additional reduction with [Na.sup.0]/THF or upon heating to approximately 500 degree Celsius.

Monitoring carbon nanotube growth by formation of nanotube stacks and investigation of the diffusion-controlled kinetics

Article Abstract:

A novel method is developed to monitor carbon nanotube (CNT) growth by formation of CNT stacks and CNT growth kinetics are investigated for densely packed CNT films in the gas-diffusion-controlled regime. The self-diffusion of gases in the densely packed CNT is found to be Knudsen diffusion with a diffusion coefficient on the order of 10(super -4) cm(super 2)/s.
