摘要/Abstract

摘要： 首次从轨道杂化的角度探讨了MIM隧道结负阻特性的成因,结合化学上的计算,并与实际测量结果进行对比分析,提出了MIM隧道结负阻特性的理论解释.

关键词: 轨道杂化, 负阻特性, MIM隧道结, 表面等离极化激元

Abstract: In this paper, we discuss the reason of the negative resistance phenomenon(NRP) existing in a MIM(metal-insulator-metal) light emission tunnel junction's I-V character by using orbital hybridization theory for the first time. Combining with chemical calculation and our experimental results, a theoretical explanation of the NRP is proposed.

Key words: negative resistance phenomenon (NRP), orbital hybridization, surface plasmon polariton (SPP), MIM light emission tunnel junction
