On page 3933 , Zabeada Aslam, Nicole Grobert, and co‐workers show that the electrical properties of multi‐walled carbon nanotubes (MWCNTs) can be manipulated by introducing dopants. The image shows the current‐induced restructuring of a N‐doped MWCNT, as a result of Joule heating. This leads to the removal of the dopant and a significant change in its electronic behaviour and has serious implications for the use of doped‐CNTs as electronic components.
