多孔硅的XPS研究
XPS Study of Porous Silicon
摘要
Abstract
The surface properties of two kinds of porous silicon(PS)samples—fresh PS which was dipped in HF solution before experiment and the aged PS which has been stored in the air for one year-were examined by X-ray photoelectron spectroscopy. The fresh PS surface has only trace O and F, O exists in the form of OH-, which is related to replacement of F- with OH- in cleaning process. The PS is gradually oxidated on the surface and SiO2 is formed, when it is stored in the air. Therefore, the fresh PS and aged PS have different surface forms, both of them have strong photoluminescence, but they have different origins of luminescence.关键词
