Triode-type Field Emitter Arrays Using Selectively Grown Carbon Nanotubes

摘要

Carbon nanotubes (CNTs) as field emitters have drawn much attention owing to their high aspect ratio more than 300 as well as high chemical inertness and mechanical strength[1]. Although there were many papers reporting the electron emission in diode configuration, the papers regarding the fabrication of triode-type CNT emitters was few. Triode-type emitters are essential for practical application in order to realize low voltage driving, high resolution and full gray-scale imaging.
