摘要
以高氢稀释硅烷为反应气源,用PECVD方法淀积了nc-Si:H薄膜。未经任何后处理过程,在低温77K下观察到光致发光,并对薄膜样品进行了Raman散射,红外吸收谱,氢氧含量以及光学吸收系数分析测试。还对nc-Si:H薄膜低温光致发光的机理进行了讨论。
The nc-Si: H films are prepared by using highly diluted silane as thereactive gas in a PECVD system. The photoluminescence on the films is observed at77 K. In addition, the spectra of Raman scattering and the infrared absorption, andthe concentrations of H and O are obtained. The mechanism of photoluminescenceof the film is discussed simply.
