Résumé
Positive magnetoresistance is measured in the low-magnetic fields in multiwalled carbon nanotubes, and interpreted as antilocalization in the weak-localization regime. The analysis shows that the weak antilocalization effect is related to the local interfacial electric field as a genuine property of the large curvature and multiwalls in the tubes. By fitting the positive magnetoresistance using the antilocalization theory, a set of scattering times in the tubes is obtained.
