FIG. 1.

Current-field plot from CNT fiber FE showing measured current with increasing field sweep and showing three operational regimes. The dashed lines represent the breakpoints between the regimes. Inset: Fowler-Nordheim plot spanning regimes I and II.

FIG. 2.

RGA showing increase in partial pressure of (a) H and (b) CO during field emission. The dashed line represents the transition between regimes I and II and represents the onset for desorption.

Image of FIG. 3.
FIG. 3.

Fit (red curve) to the experimental I-E data in the intermediate regime II shown in Fig. 1 using Eq. (4) . The individual contributions from the nanotubes with adsorbates (f I) and bare nanotubes (f I) are shown. The noise in the data is larger to the left of the field E, where f I = f I.
