[交流] 硅氢表面的稳定性

我最近在做单晶硅表面的化学单层自组装,其中需要用HF或者NH4F处理单晶硅表面成Si-H,即H-terminated silicon。
    我的问题是:Si-H表面在空气中的稳定性,即可以保留多长时间!我在用氮气吹干的过程中因为处理时间的问题会不会被氧化!
    应该怎么处理操作最好!最好附上参考文献,或者网址!
    不胜感激!

The electroless deposition of copper on the hydrogen-terminated Si(111) surface was investigated by means of
attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy, scanning tunneling
microscopy (STM), and energy-dispersive spectroscopy (EDS). The hydrogen-terminated Si(111) surface
prepared was stable under air atmosphere for a day or more. It was found from ATR-FTIR that two bands
centered at 2000 and 2260 cm−1 appeared after the H-Si(111) surface was immersed in 40% NH4F solution
containing 10 mM Cu2+. On the other hand, STM image included the copper islands with a height of 5 nm and
a diameter of 10-20 nm. The EDS data displayed the presence of copper, silicon and oxygen species. The results
were rationalized in terms of the redox reaction of surface Si atoms and Cu2+ ions in solutions, which are
changed into Si(OH)x(F)y containing SiF6
2− ions and neutral copper islands.
Key Words : Silicon, Copper, Ammonium fluoride, ATR, STM
