Correlating Disorder Microstructure and Magnetotransport of Carbon Nanowalls

نویسندگان

چکیده

The carbon nanowalls (CNWs) grown by Plasma-Enhanced CVD reveal differences in the magnetotransport properties depending on synthesis parameters. In this paper, we report influence of deposition temperature, which produces variations disorder microstructure CNWs. Relative low leads to weak localization with transition antilocalization. Higher generates positive Hopping mechanism field a crossover diffusion transport graphene nanocrystallites. samples similitude isoline density MR at temperature (<50 K), explained context magnetization. This effect is independent number defects. We can achieve desirable amount control over MT changing CNWs’ microstructure.

Ftir Investigation of the Ageing Process of Carbon Nanowalls

In this paper we investigate the changes that occur in the chemical composition of carbon nanowalls due to ageing process in open atmosphere. Ageing process of the carbon nanowalls samples was monitored for about two years by FTIR spectroscopy. The carbon nanowalls were deposited in a low-pressure plasma jet expanding through a nozzle. The ageing behaviour of the samples is related to the time ...

investigation of the electronic properties of carbon and iii-v nanotubes

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...

Effects of Carbon on the Microstructure and Hot Deformation Behavior

The effects of carbon content on the dynamic and static softening mechanisms of Ti microalloy steels were investigated both in ferrite and austenite regions. &#10The results obtained showed that recrystallization rate decreased as the percentage of carbon content was increased from 0.0035 to 0.110. This is due to the Ti(CN) and TiC precipitates and also the free carbon content. In the ferrite r...
