“…The CNT emitter fabricated by the filtration-taping method demonstrates the best field emission performance: the lowest turn-on electric field of 0.88 V/ µm at an emission current density of 0.1 A/cm 2 and a threshold electric field of 1.98 V/µm at an emission current density of 1 mA/cm 2 , and the largest field enhancement factor of 3337. The achieved field emission performance is much higher than those of the previous results [8,[22][23][24]. We consider that the largest field enhancement factor also confirms the vertical alignment of CNTs in the filtration-taping field emitter.…”

A filtration-taping method 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 field emission performance with a turn-on field of 0.88 V/mm at a current density of 0.1 mA/cm 2 , a threshold field of 1.98 V/mm at a current density of 1 mA/cm 2 , and a good stability of over 20 h. The filtration-taping technique is an effective way to realize low-cost, large-size, and high-performance CNT emitters.

“…The out-gassing from the CNTs cathode is one of the main reasons of vacuum deterioration, resulting in degradation of emission currents. [29] In addition, the structural modifications of nanotube tip by the ion bombardment of residual gases could reduce the emission current at high electric field region. Therefore, the stability of CNTs would depend on its mechanical strength and chemical reactivity.…”

In this paper, we tried to increase the current density of carbon nanotubes (CNTs) by depositing double layer of CNTs instead of single layer. Both the layers of CNTs are deposited by the low pressure chemical vapour deposition technique on silicon substrate with Fe catalyst. Scanning electron microscopic images show the surface morphology of single and double layer of CNTs. Dual layer deposition of CNTs is a very simple and easy method to increase the current density of CNTs based field emitters than other conventional methods. Excellent field emission properties of double layer of CNTs are exhibited with large field enhancement factor and low turn-on voltage as compared to those for single layer of CNTs. High current density of CNTs is required for field-emission-based display devices associated with field enhancement factor and number of emitting electrons. Therefore, we may say that dual layer deposition of CNTs can be utilised as an alternative approach to improve the current density for field emitters. Stability measurement of the samples was also performed for 3 h (180 min) with current at constant applied voltage, and it was found that the stability of dual layer of CNTs is remarkable than that of single layer of CNTs.

“…CNTs thin films consisting of multi-walled CNTs (MWCNTs) are fabricated by the spray method, which is an easy and convenient method to deposit CNTs and can achieve large area deposition [43]. The procedures of the fabrication of CNTs template are described as below: First CNTs are suspended in 1, 2-dichloroethylene (DCE) and second, sonication of 30 mg CNTs in 50 ml DCE solvent for 2 hours.…”
