J Nanosci Nanotechnol
. 2006 Jun;
6(5):1350-6.
PMID: 16792364
Electron beam induced structural transformations are investigated in single-wall carbon nanotubes (SWNTs), double-wall carbon nanotubes (DWNTs) and crossed nanotube junctions. The nanotubes studied here are synthesized by the chemical vapor...
