Si nanostructures in different forms (nanowires, nanodots, nanorods, nanoribbons, etc) are rationally synthesized using various methods. Si nanowires and quantum dots are shown to have unique and interesting structural, optical, electronic, chemical, and sensing properties. Si nanowire-based FETs reveal remarkable ambient effects on the transport properties, demonstrating the importance of surfaces in determining nanomaterials properties. The various unique properties enable Si nanowires arrays to have myriad exciting application potentials, e.g. in solar cell, battery, catalyst, chemical and biological sensing. Similarly, Si nanoparticles are shown to possess unique properties leading to promising applications in catalysts and bioimaging.
