A periodic contribution with a period of 18 T corresponding to the magnetic flux quantum A c/e per nanotube cross section has been revealed in the longitudinal magnetoresistance. The result points to the possibility of the ballistic motion of the carriers over the sample perimeter under conditions close to their strong localization in the longitudinal direction.","pubDate":"2026-10-20","url":"https://hal.science/hal-00997893"},"indexado":"2026-10-20T12:23:04.288Z"}}
