Field emission properties of boron nitride (BN) nanomaterials have been studied for years to apply it at harsh ambient condition. However, the field emitters fabricated using the BN nanomaterials have limitations to utilize it as field emission devices due to their poor emission performances. Here, we report much enhanced field emission properties of the BN nanomaterial with low turn-on electric field,...
Boron nitride nanotubes (BNNTs) have been studied as a field emission material due to their unique and excellent properties such as high oxidation resistance and negative electron affinity. However, field emission properties of BNNT field emitters were rarely reported until now because it is difficult to synthesize high purity BNNTs and fabricate stable BNNT field emitters. Here, we report high field...
Boron nitride (BN) nanomaterials have negative electron affinity, which makes BN a promising cold electron emission material. BN nanotube (BNNT) field emitters show excellent oxidation endurance after high temperature thermal annealing at 600 °C in air ambient. There is no damage to the BNNTs after the thermal annealing at a temperature of 600 °C and also no degradation of field emission properties...
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...
