Abstract :
In this work, electron field emission from AAO-CNT structure is studied as a function of anodizing voltage. It is found that the turn-on electric field of AAO-CNTs reduces from 5 V/¿m to 4 V/¿m as anodization voltage increase from 20 to 30 V. On the other hand, CNTs the turn-on electric field of AAO-CNTs increases from 4 V/¿m to 6 V/¿m as anodization voltage increase from 30 to 40 V. SEM and F-N analyses can explain the effect of anodization voltage on field emission from AAO-CNTs based on field screening effect.
