Geometrical dependence of high-bias current in multiwalled carbon nanotubes
Physical Review Letters, 2004•APS
We have studied the high-bias transport properties of the different shells that constitute a
multiwalled carbon nanotube. The current is shown to be reduced as the shell diameter is
decreased or the length is increased. We assign this geometrical dependence to the
competition between the electron-phonon scattering process and Zener tunneling.
