摘要: 本文报道了MIM隧道二极管的发光和负阻现象,用梯形势垒计算了电流-电压特性。结果显示,由于SPP波对电子的阻挡和束缚作用引起的势垒平均宽度的增加所导致的负阻现象与实验结果相符合。

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. -
