摘要
金属／绝缘层／硅（ＭＩＳ）隧道发光二极管的发光机理可以归结为表面等离极化激元（ＳＰＰ）与界面粗糙度的耦合．电流－电压特性曲线中６．５Ｖ附近的一个负阻和发射光谱中４７５ｎｍ的峰显示，在硅／二氧化硅界面激发起了与之相应的等离子体振荡．
Abstract Light emission from Metal/Insulator/Silicon (MIS) tunnel diode can be attributed to
that the Surface Plasmon Polariton (SPP) is coupled to photon by surface roughness. In our
experiments, the Negative Differential Resistance (NDR) is occured around 6 5 volt in the
current voltage curve of MIS tunnel diode, and a radiative peak is near 475nm on its light
emission spectrum. From these we consider that the surface plasma can be coupled to
emissive photons which are excited in silicon of MIS tunnel diode.
