Abstract

original image

The morphology of individual carbon nanotubes is precisely engineered by positive field evaporation and this process is monitored in situ by transmission electron microscopy, as shown in the figure. The evaporation process enables accurate control over the grinding and shortening of the nanotubes and the opening of their end caps.
