Carbon nanotube devices emit high current density

Abstract:
Researchers at the Naval Research Laboratory (NRL), US, have made carbon nanotube arrays that can produce a field emission current density of 1.2 A/sq. cm for a gate voltage of just 60 V. The devices contained arrays of carbon nanotubes grown by chemical vapour deposition on microfabricated template structures with integral gates.
