On-chip electron-impact ion source using carbon nanotube field emitters
Abstract
A lateral on-chip electron-impact ion source utilizing a carbon nanotube field emission
electron source was fabricated and characterized. The device consists of a cathode
with aligned carbon nanotubes, a control grid, and an ion collector electrode. The
electron-impact ionization of He, Ar, and Xe was studied as a function of field emission
current and pressure. The ion current was linear with respect to gas pressure from
10-4 to 10-1 Torr. The device can operate as a vacuum ion gauge with a sensitivity
of approximately 1 Torr-1. Ion currents in excess of 1 μA were generated. © 2007 American
