Abstract
Field emission characteristics of carbon nanotubes (CNTs) grown on Fe-coated glass using mixed gases of CO and NH3 were investigated by varying the growth time and growth condition including in situ re-etching and/or re-growth of CNTs. An increase in growth time resulted in a reduction of a turn-on electric field. However, additional in situ re-etching and re-growth of CNTs after the initial growth yielded a decrease in the emission current from CNTs with a similar turn-on field to as-grown CNTs.
