Field ionization detection of helium using a planar array of carbon nanotubes

In this work we demonstrate the field ionization of neutral helium using a carbon nanotube forest in a parallel-plate detector geometry. The nanotube forest was grown using plasma-enhanced chemical vapor deposition on a silicon substrate. With a high positive voltage applied to the nanotubes, the me...
