Evidence for adsorbate-enhanced field emission from carbon nanotube fibers

P. T. Murray, T. C. Back, and M. M. Cahay et al.

We used residual gas analysis (RGA) to identify the species desorbed during field emission (FE) from a carbon nanotube (CNT) fiber. The RGA data show a sharp threshold for H2 desorption at an external field strength that coincides with a breakpoint in the FE data. A comprehensive model for the gra ... [Appl. Phys.
