【摘要】 碳纳米管(CNT)具有良好的场发射特性,研究表明,垂直于基板的碳纳米管具有较其他取向更大的场发射能力,本文介绍一种在大面积基板上使碳纳米管取向垂直的方法,通过有关参数的实验测试,研究了解场发射能力提高程度,并估算场增强因子。本方法对制备大屏幕场发射显示器(FED)具有积极意义。更多还原

【Abstract】 Carbon nanotube(CNT)possesses favorable field emission characteristic. Studies indicate that carbon nanotube present along perpendicular orientation have better field emission competence than other orientation. In this paper, a method to make carbon nanotube present along perpendicular orientation on big area was depicted. Through testing relative parameters, we study improving field emission competence, as well as estimating field strength factor. This method is meaningful to deposit big screen field emission display(FED).更多还原
