摘    要:将nc-Si:H薄膜进行等离子和高温氧化处理,测量了样品的氢,氧含量,Raman谱,红外吸收谱,光致发光(PL),结果表明两种氧化方式都将氧掺入薄膜中,但不同处理方式氧在薄膜中的键合形式不同Raman谱表明氧化处理对薄膜中晶粒大小及晶态比没有影响,用晶粒-表面模型对氧化引起的光致发光(PL)蓝移进行了解释。

关 键 词:光致发光  表面复合  量子效应  表面态

Abstract:The hydrogenated nano crystalline silicon (nc Si:H) films are prepared using conventional plasma enhanced chemical vapor deposition (PECVD) method and oxidized by plasma and high temperature treatment which both doped oxygen into nc Si:H film. The contents of hydrogen and oxygen, the infrared absorption spectra, photoluminescence (PL) spectra are measured. The PL peak wavelength blue shifts from 720nm to 660nm at 77K, which can be explained by grain surface model. The bonded forms of oxygen in nc Si:H are changed with different oxidized way and their influence on PL spectra is also investigated.
Keywords:photoluminescence  surface recombination  quantum effects  surface states
