摘要
本文给出了硅表面覆盖氧化层时,场发射电流的解析公式.考虑了固定氧化物电行时场致发射的影响.结果表明,氧化物和固定电荷均使场发射电流减小,场发射Fowler-Nordheim图中有两个明显的线性区.
Abstract Taking into account the fixed charge within the oxide, an analytical formula for field emission from the oxide-covered silicon is presented. The results show that both the oxide film and the fixed charge reduce the field; emission current. The Oxide films over about 1nm in thickness result in the two-distinct linear regions in Fowler-Nordheim plot.
