- Abstract
- We report the controlling of e-beam trajectory by the tapered macro-gate (TMG) proposed for carbon nanotube (CNT) field emitters in the last year. The TMG has relatively tall and tapered holes, showing a high e-beam focusing and perfect shielding of CNT emitters from the anode voltage for field emission display (FED). For FE lamp application, we modified the TMG to have two separate gate electrodes against gate holes. The alternating driving of the two gate electrodes of the modified TMG showed a wide e-beam spreading suitable for FE lamp.
