We measure zero-field resistivity and magnetoresistance of multiwalled carbon nanotube yarns (CNTYs). The CNTYs are drawn from superaligned multiwalled carbon nanotube arrays synthesized by the low-pressure chemical vapour deposition method. The zero-field resistivity shows a logarithmic decrease from 2 K to 300 K. In the presence of a magnetic field applied perpendicular to the yarn axis, a pronounced negative magnetoresistance is observed. A magnetoresistance ratio of 22% is obtained. These behaviours can be explained by the weak localization effect.

The stabilization ratios 𝑅 for double-electron transfer, i.e., the cross section ratios of true double capture to total double-electron transfer, are measured in O 6+ +He, Ne and Ar collisions at 6 keV/𝑢. A high 𝑅 value about 68% is obtained for the He target, while for the Ar target, the 𝑅 value is only 8%. The high 𝑅 value for the He target is due to the significant direct population of the (2𝑙, 𝑛𝑙 ′ ) configurations with high 𝑛. For the Ar target, the (quasi)symmetric configurations (3𝑙, 𝑛𝑙 ′ ) lead to the much lower 𝑅 value. Neglecting the core effects, the O 6+ ion can be taken as a bare ion C 6+ except the occupied 1s shell, and then the measured 𝑅 values are compared with previous experimental results of C 6+ projectile ions at similar impact velocity. It yields good agreement with the Ne and Ar target, while the occupied 1s shell for the O 6+ +He system results in a higher 𝑅 value than that in C 6+ +He collisions.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
