The screen printed nano-SiC film for field emission

In this paper, the low-cost screen printed method was adopted preparation uniform nano-SiC films on large areas of glass. The reunited nano-SiC was dispersed by ultrasonic before fabricating paste. After fabricating paste, the nano-SiC was further ultrasonic dispersed. The nano-SiC paste was screen printed on glass. Then nano-SiC films was sintered by the furnace controlled artificial intelligence, the anneal test was take to improve the field emission characteristics. The samples of nano-SiC film were micro-analyzed and tested the I-V characteristics. After above experiments and technics, the uniformity and stability of field emission characteristics for nano-SiC film was obtained.
