Abstract :
A multiwalled carbon nanotube (MWCNT) was assembled onto a tungsten tip in a transmission electron microscope (TEM). Then it was transferred into a field-emission microscope (FEM) for the measurement of field emission properties. Stable field emission current and pattern were established after an aging process, which ridded the MWCNT of adsorption and blunted its end. A reduced brightness of 107-108(A/m2middotsrmiddotV) was eventually obtained
