The results show that the best field emission characteristic is measured with an enhancement factor of around 2118, and a turn-on field intensity of 6.3 V/m were obtained.

- 這表示在較低長(cháng)度之下，增加奈米線(xiàn)的長(cháng)度有助于提升其場(chǎng)發(fā)射特性，但是到了一定長(cháng)度之后，此時(shí)繼續的增加奈米線(xiàn)的長(cháng)度將使得電場(chǎng)屏障效應增加，導致場(chǎng)發(fā)射特性隨著(zhù)長(cháng)度的增加而衰減。
