摘要：

We report associated high-resolution transmission electron microscopy (HRTEM) and transport measurements on a series of isolated multiwalled cart on nanotubes. HRTEM observations, by revealing relevant structural features of the tubes, shed some light on the variety of observed transport behaviors, from semiconducting to quasi-metallic type. Non-Ohmic behavior is observed for certain samples which exhibit "bamboo-like" structural defects. The resistance of the most conducting sample exhibits a pronounced maximum at 0.6 K and strong positive magnetoresistance.
