    Carbon Nanotube Field Emitters. We are developing Carbon Nanotube (CNT) field emitters to improve their efficiency and durability. Current densities of ~1A/cm2 have been measured from these emitters. X-ray tubes, built with these CNT bases cathodes, have shown improved efficiency and robustness. Increase in electrical conservation and thermal management can be realized …

    Carbon nanotubes have a range of electric, thermal, and structural properties that can change based on the physical design of the nanotube. Single-walled carbon nanotube structure Single-walled carbon nanotubes can be formed in three different designs: Armchair, Chiral, and Zigzag.

Carbon nanotube films as electron field emitters ...

    https://www.sciencedirect.com/science/article/pii/S0008622302000118
    Carbon nanotubes have been recognized as one of the most promising electron field emitters currently available. We review the state of the art of current research on the electron field emission properties of carbon nanotube films and present recent results outlining their potential as field emitters as well as illustrating some current concerns in the research field.

    CNT-based field emitters with various array pattern configurations were prepared by a screen-printing method with CNT paste, as shown in Fig. 1(a). The emitter patterns were prepared with different numbers and diameters of the unit dot within the same total area of 0.008 cm 2.This resulted in 44, 16, 6, 1 unit dots within diameters of 150, 250, 400 and 1000 μm, …
