Abstract
The instability of the electron field emission from a standalone multiwalled carbon nanotube with and without an insulator barrier has been investigated. The insulator barrier is an amorphous carbon layer formed by electron beam induced deposition and removed by a heat treatment during the field emission in situ. It is found that the emission current is quite noisy when the tip is covered with the amorphous carbon layer but stable after removing it. The instability is discussed in term of the applied voltage dependence of the noise frequencies and the behavior of the bright spots in the field emission microscope images.
