Abstract

The printed carbon nanotubes (CNTs) on the substrate were stood erect by the laser treatment and they worked as emission sites. The emission characteristics was improved drastically by the laser treatment up to the turn-on voltage 2 V//spl mu/m and the current density 4 mA/cm/sup 2/, approximately. A certain level of height of CNT (approximately 3 /spl mu/m) is necessary to lower the turn-on voltage and reduce emission variation effectively.

激光处理后碳纳米管阴极的发射特性

通过激光处理，将打印出来的碳纳米管竖立在衬底上，作为发射点。在导通电压为2 V//spl μ m，电流密度约为4 mA/cm/sup 2/时，激光处理大大改善了材料的发射特性。为了有效降低导通电压和减小发射变化，需要一定的碳纳米管高度(约3 /spl mu/m)。
