A filtration-tapingmethod was demonstrated to fabricate carbon nanotube (CNT) emitters. This method shows many good features, including high mechanical adhesion, good electrical contact, low temperature, organic-free, low cost, large size, and suitability for various CNT materials and substrates. These good features promise an advanced fieldemission performance with a turn-on fieldof 0.88 V/mm at a current density of 0.1 mA/cm2, a threshold fieldof 1.98 V/mm at a current density of 1 mA/cm2, and a good stability of over 20 h. The filtratio-taping technique is an effective way to realize low-cost, large-size, and high-performance CNT emitters.
