Hot nanotubes: stable heating of individual multiwall carbon nanotubes to 2000 k induced by the field-emission current.

Abstract

Field emission (FE) electron spectroscopy from an individual multiwalled carbon nanotube (MWNT) is used to measure quantitatively stable temperatures at the apex, T(A), of up to 2000 K induced by FE currents approximately 1 microA. The high T(A) is due to Joule heating along the length of the MWNT. These measurements also give directly the resistance of the… (More)
