Abstract :
The effect of thermal annealing on the field emission properties of double-walled carbon nanotubes (DWCNT) grown by chemical vapour deposition is studied. The properties of the DWCNTs were examined using SEM, TEM, Raman and TGA analysis. It was found that high-temperature annealing enhances the field emission performance of DWCNTs
