Keywords： CeB6

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.
