Fullerene whiskers

[1] Fullerene whiskers and tubes are held together by weak van der Waals forces, and hence are very soft.

They are semiconductors and have potential uses in field-effect transistors, solar cells, chemical sensors, and photocatalysts.

When doped with alkali metals, such as potassium, they become superconductors at 18 K (−255.2 °C; −427.3 °F).

[2] As-grown fullerene nanotubes have hexagonal shapes and face-centered cubic crystal structures.

100 nm) and low reactivity they can accommodate a wide range of nanoparticles.
