从排列和打开的碳纳米管阵列中获得了非常低的场发射。在0.6 ~ 1 V/μm的场发射电流密度可达10微安/平方厘米，在2 ~ 2.7 V/μm的场发射电流密度可达10 mA/cm2。这些电场比之前碳纳米管获得的电场低2倍以上，并且代表了在相同电流密度下任何场发射阵列所报道的最低场，表明碳纳米管是优越的场发射体。
A very low-field emission was achieved from aligned and opened carbon nanotube arrays. Field emission current densities of 10 microamperes per square centimeter were observed at applied fields of 0.6−1 V/μm, and current densities of 10 mA/cm2 have been realized at applied fields as low as 2−2.7 V/μm. These fields are more than 2 times lower than those previously obtained for carbon nanotubes, and also represent the lowest field ever reported for any field emitting arrays at the same current densities, indicating that carbon nanotubes are superior field emitters.
