文摘
We report on in situ UV鈥搗is spectroscopic measurement during the electrodeposition of silicon, germanium, and silicon鈥揼ermanium alloys from an ionic liquid. From the spectroscopic analysis, the potential-dependent formation and growth of Ge, Si, and SixGe1鈥?i>x nanoparticles were evaluated. The possible formation of adlayers and an underpotential deposition of Si on Ge during silicon and germanium electrodeposition are also discussed.
