摘要：
Carbon nanotubes (CNTs) were screen-sprinted on a patterned indium tin oxide (ITO) substrate and irradiated using an ultra violet (UV) laser. The emission characteristics of screen-printed CNTs were tested with a diode structure with a spacer of 125 mum. The electron emission current increased from 10 muA to 300 muA, and the turn-on voltage decreased from 300 V to 320 V C with laser irradiation, corresponding to an electric field from 3.6 V/mum to 3.2 V/mum. The emission sites were also increased with laser irradiation, CNT samples, deposited on the Al film by electrophoresis. were also irradiated with an UV laser, giving rise to a slight increase in emission current with few increases in the number of emission sites.
