摘要：
Field emission characteristics of carbon nanotube (CNT) and BCN samples are investigated at various ambient pressures. The threshold electric field increases with increasing ambient pressure for both samples. However, it is found that the threshold electric field of the CNT sample begins to increase at an ambient pressure region higher than 3 X 10(-5) Torr, while the no variation in the threshold electric field of the BCN sample occurs at an ambient pressure lower than 3 X 10(-4) Torr. A significant degradation of the field emission characteristics appears at an ambient pressure higher than 1 X 10(-3) Torr. It is demonstrated that degradation of the field emission characteristics of CNT sample is effectively improved by coating with BCN film. (C) 2009 American Vacuum Society [DOI: 10.1116/1.3093893]
