Figure 2: Morphology and microstructure of the prepared CNT forest and CNT–NbC composite.
From: Highly aligned carbon nanotube forests coated by superconducting NbC
(a) SEM image of a highly aligned CNT forest, (b) HRTEM image of CNTs, (c) SEM image of as-synthesized CNT–NbC composite, and (d) HRTEM image of NbC-coated CNT. Insets show the magnified SEM image of CNT forest (a), the high-resolution electron microscopy image of the as-grown multi-wall CNTs (b), and the magnified SEM image CNT–NbC composite (c), respectively.
