    • Graphenated carbon nanotubes for enhanced electrochemical double layer capacitor performance 

      Stoner, Brian R; Raut, Akshay S; Brown, Billyde; Parker, Charles B; Glass, Jeffrey T (Applied Physics Letters, 2011-10-31)
      This letter reports on nucleation and growth of graphene foliates protruding from the sidewalls of aligned carbon nanotubes (CNTs) and their impact on the electrochemical double-layer capacitance. Arrays of CNTs were grown ...
    • 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 ...
