Abstract :
Field emission is measured for various multiwalled carbon nanotubes (CNTs) prepared from chemical vapor deposition (CVD) methods or metal-(or glass-) pasted printing techniques. Among the samples, the thermal CVD grown CNT and silver-pasted CNT samples show enhanced electron emissions upon laser light irradiation corresponding to the wavelengths of 266 and 532 nm. The reasons behind this behaviour are explained in this paper
