Abstract

The outstanding field emission characteristics of Carbon Nanotubes (CNT) offer promising potential for a wide range of vacuum electronics applications. In this study, short (1 μm) CNT arrays were grown selectively on SiO2/Si substrates using ferrocene/xylene catalyst source. High field emission current density of 366.7 mA/cm2 was obtained. A common field enhancement factor (β) value of 326 was obtained for CNT bundles with various separation distances.

短碳纳米管束的场发射特性

碳纳米管(CNT)优异的场发射特性为其在真空电子学领域的广泛应用提供了广阔的前景。在本研究中，采用二茂铁/二甲苯催化剂源，在SiO2/Si衬底上选择性地生长了短(1 μm)碳纳米管阵列。获得了366.7 mA/cm2的高场发射电流密度。不同距离碳纳米管束的场增强因子(β)均为326。
