If we can effectively utilize silicon ICs advantage of process technology to combine the photoelectric component, the photonic-chip system will be realized. In this project, the purpose is major using slicon nano structure to develop novel erbium-doped slicon(Er-Si) nanocrystal-based light emitting devices with transparent conductive oxide (TCO) contacts and surface structure modifications, which can break indirectness energy gap (Eg) of low compound quantum efficiency limitation, and give out light efficiency effectively. Our direction will plan to study the structure of Er-Si array nanocrystal-based, preparation of Er-doped ZnO (EZO) TCO contacts, fabrication of Er-Si array nanocrystal-based devices, surface structure modification of Er-Si array nanocrystal - based devices, and novel EZO array devices. The research subject will include microstructure, surface, PL, EL, and other physical properties of the different density of the nano-rod/pyramid with high aspect-ratio, EZO contacts, and novel EZO array. Furthermore, we also focus on investigation of Fowler-Nordheim tunneling effect and charging effect of Er-Si array structure and novel EZO array structure. We attempted to understand about the nano structure device, which performed in the role of electrics transmission conversion at luminescence state, and established the optimum process conditions; moreover, providing the important knowledge and experience for slicon-based light emitting devices and field of nano ICs science and technology.矽基發光元件透明導電氧化物電極表面奈米糙化結構Novel Erbium-Doped Silicon Nanocrystal-Based Light Emitting Devices with Transparent Conductive Oxide Contacts and Surface Nano-Roughened Structure透明導電氧化物電極與表結構修飾於新穎陣列式奈米摻鉺矽基發光元件之研究
