【摘要】 我们在研究MIM隧道发光结(金属-绝缘层-金属)的过程中,首次以表面声波代替表面随机粗糙度的作用,将MIM结制作在声表面波场中,结果使结的发光效率、发光强度、稳定性、均匀性都有改善.本文介绍了结的基本结构,基本工艺,阐明了结的发光机理,讨论了结的I—V特性曲线和光谱曲线,根据结具有显著的负阻现象,我们设计出了一种新型的开关器件.更多还原

【Abstract】 In the study of MIM (Metal-Insulator-Metal) LETJ (light-emission tunneling junction), we adopted SAW (Surface Acoustic Wave) instead of surface roughness and fabricated MIM LETJ in the field of SAW. As a result, the LETJ’s efficiency, intensity and stability have been advanced obviously.In this paper, we introduce the LETJ’s basic structure and technology , explain its light-emission theory, discuss its Ⅰ-Ⅴcharacteristics curve and spectrum,devise a new type of switch on the basis of negative resistance phenomenon.更多还原
