%X The temperature dependence of field emission from multiwalled carbon nanotubes deposited on a W tip was studied. It is found that the emission current increases with increase of temperature, while the stability of the emission current did not change. The field emission characteristic deviates from classic Fowler-Nordheim theory. This may result from a dispersion in the field enhancement factor of the carbon nanotubes.
