[구두발표]Improved Electrical and Thermal Properties of Doped MWCNTs Synthesized by Direct Current Arc Discharge Technique
•Arc-CNTs are promising for field emitter materials thanks to their excellent crystallinity and straightness, compared to CVD-CNTs.
•Boron (B) has been known as oxidation inhibitors of carbon materials. During field emission, CNT emitters undergo severe degradation due to Joule heating. It is expected that B doping would improve the thermal stability of CNT emitters.
•This study investigates fabrication of B-doped MWCNTs using electric arc discharge, where B dopants were introduced from anode electrodes, and their field emission performances.
•We further expect that B doping may gives rise to change of CNT geometry of arc-CNTs such as diameters, which will also affect field emission properties.
