Tuning the Tailored Single-Walled Carbon Nanotubes by Highly Energetic Heavy Ions

El-Said, A. S.; Rao, S.; Akhmadaliev, S.; Facsko, S.
Carbon-based nanomaterials have attracted a lot of interest lately due to their highly promising applications. Here, we report on the modifications of single-walled carbon nanotubes (SWCNTs) induced by swift (highly energetic) heavy ions. Using scanning force microscopy and Raman spec- troscopy, we observed a dramatic change in the structure of the irradiated SWCNTs, accompanied by an increase of the adhesion force as a function of ion fluence and electronic energy loss. With increasing ion fluence the SWCNTs exhibit a partial transformation from metallic to more semicon- ducting. Moreover, at high fluence they break into segments of 10–20 nm length.
