A new triode structure for field emission displays based on carbon nanotube
emitters is demonstrated. In this structure, gate electrodes are located u
nderneath the cathode electrodes with an in-between insulating layer, a so-
called under-gate type triode structure. Although the gate is on the opposi
te side of the anode with respect to the cathode electrodes, modulation of
electron emission from the carbon nanotube emitters by the gate voltage is
confirmed. The simple structure and fabrication process may lead to practic
al applications for the under-gate triode type structure. (C) 2001 Publishe
