Improvement of Electron Field Emission from Carbon Nanotubes by Ba(NO3)2 Treatment

The method of manufacturing BaO thin layers on carbon nanotubes (CNT) from Ba(NO3)2 aqueous solutions was demonstrated. Ordered carbon nanotubes arrays were synthesized by catalytic plasma-stimulated chemical deposition from the gas phase. The influence of the BaO content on the work function and, a...

Zusammenfassung:The method of manufacturing BaO thin layers on carbon nanotubes (CNT) from Ba(NO3)2 aqueous solutions was demonstrated. Ordered carbon nanotubes arrays were synthesized by catalytic plasma-stimulated chemical deposition from the gas phase. The influence of the BaO content on the work function and, accordingly, carbon nanotubes emission properties were investigated. Significant field emission threshold voltage of CNT arrays treated by solutions with the lowest Ba(NO3)2 concentrations was demonstrated.
