In this project structured deposits of silicon, germanium and of SiGe shall be made electrochemically in ionic liquids. The codeposition of silicon and germanium gives a material which changes its colour during deposition, likely due to a quantum confinement effect. With UV/Vis spectroelectrochemistry and XPS-measurements a deeper insight into the formation and the binding properties shall be obtained. Nanostructured silicon is of high interest as material in future lithium-ion-batteries , as such a material would allow higher energy densities than the usual lithium/graphite intercalation compounds. Both macroporous silicon and macroporous lithium/silicon shall be made. Furthermore it shall be investigated in more detail how the recently found solvation layers of ionic liquids behave during semiconductor deposition and how they influence the determination of the band gap by tunneling spectroscopy.

在这个项目中，硅，锗和锡岩的结构化沉积物应在离子液体中进行电化化。硅和锗的代码给出了一种在沉积过程中改变其颜色的材料，这可能是由于量子限制效应所致。使用UV/Vis SpecroelectroChemistry和XPS测量，应更深入了解地层和结合特性。纳米结构的硅作为未来锂离子爆发物中的材料引起了人们的兴趣，因此，这种材料将使能量密度高于通常的锂/石墨插入化合物。大孔硅和大孔/硅都应制成。此外，应更详细地研究它在半导体沉积过程中最近发现的离子液体的溶剂化层如何影响它们如何通过隧道光谱法影响测定带隙的确定。
