中文摘要：
多孔硅纳米线是一种新型多孔材料。其不仅保持原硅衬底的电学性能，而且有宏观硅所不具有的荧光效应。结合其大比表面积、丰富的化学反应活性、生物兼容性和可降解性，其将在光学、电子器件、光电器件、传感器、能源转换和生物领域中获得广泛的应用。但是目前多孔硅纳米钱的进展存在如下局限性（a）孔的形成机制并没有完全被理解。可控的孔径，孔分布密度和有序度对很多应用都非常重要。（b）多孔硅纳米线的表面化学还没有被广泛研究。（c）从不同衬底所生长的多孔硅纳米线的物理和化学性能缺乏系统研究。本项目将注重于对不同硅衬底上多孔硅纳米线机制进行系统研究并注重于孔径尺寸、孔深、孔密度和有序度的控制；系统研究多孔硅纳米线的物理化学性能，并研究表面修饰对其性能带来的变化；多孔硅纳米线作为生物传感器，气体传感器和重金属离子检测的应用性研究。
