Field emission from single-crystalline CeB6 nanowires

We presented a field electron emission measurement of single crystalline CeB6 nanowires. The nanowires exhibited a low turn-on electric field (7.6 V/μm at 10 μA/cm2), and the deviation of Fowler-Nordheim (F-N) plots from straight line was observed in field electron emission measurements. The field enhancement factors were obtained by separate straight line fitting. The nonlinearity in the F-N plots may be attributed to the non-uniform field electron emission of CeB6 nanowires. The field emission properties of the CeB6 nanowires indicated a competitive candidate for field-emission-based application.
