Au/锗/氧化硅纳米多层膜/p-Si结构的电致发光机制研究
Study of electroluminescence mechanism in Au/Ge/SiO2 nanometer multi-layer films /p-Si structure
【摘要】 用射频磁控溅射法制备了锗/氧化硅纳米多层膜,在室温下测量了Au/锗/氧化硅纳米多层膜/p-Si结构的电致发光。利用位形坐标模型分析了锗/氧化硅纳米多层膜的发光中心,并用量子限制-发光中心模型对该纳米结构的电致发光过程作了研究,研究表明锗/氧化硅纳米多层膜的电致发光主要来自SiO2层的发光中心。
【Abstract】 Ge/silicon oxide nanometer multilayer films were deposited by the r.f.magnetron sputtering technique.The electroluminescence spectra from Au/Ge/SiO2 nanometer multilayer films/p-Si were measured at room temperature.The light centers of this structure are analyzed by using configuration coordinate,and the electroluminescence process of this structure is studied by using quantum confinement-luminescence center model.The results show that the EL of Ge/silicon oxide nanometer multilayer films originates mainly from luminescence centers of SiO2 layers.
