Deposition of magnesium silicide nanoparticles by the combination of vacuum evaporation and hydrogen plasma treatment

抄録

The radio frequency plasma enhanced chemical vapor deposition (PECVD) of the hydrogenated amorphous silicon (a-Si:H) combined with the vacuum evaporation of magnesium followed by the hydrogen plasma treatment has been successfully applied for the in-situ deposition of magnesium silicide nanoparticles embedded in hydrogenated amorphous silicon thin layers. The homogeneous coverage of a-Si:H surface by magnesium silicide nanoparticles with diameter below 10 nm has been confirmed by the scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS).
