    • A Study of Field Emission Based Microfabricated Devices 

      Natarajan, Srividya (2008-04-25)
      The primary goals of this study were to demonstrate and fully characterize a microscale ionization source (i.e. micro-ion source) and to determine the validity of impact ionization theory for microscale devices and pressures ...
    • On-chip electron-impact ion source using carbon nanotube field emitters 

      Bower, Christopher A; Gilchrist, Kristin H; Piascik, Jeffrey R; Stoner, Brian R; Natarajan, Srividya; Parker, Charles B; Wolter, Scott D; ... (8 authors) (Applied Physics Letters, 2007-03-30)
      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 ...
