Abstract
Boron nitride (BN) nanomaterials have excellent electrical, chemical and mechanical properties, such as high thermal conductivity, resistant to oxidation, chemical inertness, and negative electron affinity. These unique features make BN a promising cold electron emission material. In this work, we investigated on the field emission properties from BN nanotubes (BNNTs), among the various BN allotropes. BNNT is a tubular structured material like a carbon nanotube. The BN nanomaterial based field emitters were fabricated by a screen printing method. The screen printed BN emitters performed good field emission properties that presented good long-term stability and a high emission current. The detail field emission properties will be discussed.
