摘要: 本文報道了MIM隧道二極管的發(fā)光和負阻現(xiàn)象,用梯形勢壘計算了電流-電壓特性。結(jié)果顯示,由于SPP波對電子的阻擋和束縛作用引起的勢壘平均寬度的增加所導(dǎo)致的負阻現(xiàn)象與實驗結(jié)果相符合。

Abstract: This paper reports the light emission from MIM tunnel diode and Negative Differential Resistance (NDR) in its I-V characteristic curve. By building the trapezoid potential barrier model and calculating the numerical solution of I-V characteristic curve with computer, it is found that the increment of potential barrier average width is agree with the experiment well. This increment of potential barrier average width is caused by the SPP s impeding and trapping effect upon tunneling electrons. -
