摘要
本文研究了一种掺有稀土元素D_y的Al-Al_2O_3-D_y-Au发光隧道结新结构。并认为表面等离子体极化激元中的快模还是慢模在发光中占有优势、取决于制作工艺和结的物理结构所决定的结的粗糙度,快模和慢模在发光中具有同等的地位;D_y元素的掺入增加了结的发光强度;对伏安特性曲线中的负阻现象用离子晶体中电子自陷态理论进行了解释。
A new MIM structure (Al-Al_2O_3-Dy-Au) of light Emissim tunnel junction on a glass slide which contains the rare earth element Dy has been researched. We can obtain that the predominant intensity of light emission either from fast mode or from slow mode of surface plasmon polariton is determined by the junction roughness which depends on the technological process and their structures. We consider the role of fast mode is equal to that of slow mode in the light emission from MIM junction. Rare earth element Dy in these samples enhances the intensity of the radiation The negative resistance phenomenon in the current-voltage curves of our MIM structure is interpreted by the theory of trapped states of electron in ion crystal.
