Gas-Phase Growth of Heterostructures of Carbon Nanotubes and Bimetallic Nanowires
Figure 4
SEM images of the foxtail-like CNTs grown on Ni-Al bimetallic NWs at a residence time of (a) approximately 25 s (average length of CNT: ~ nm) and (b) approximately 5 s (average length of CNT: ~ nm) in the thermal CVD reactor (the insets show high-resolution SEM images).
