Fabrication of Silicon Nanowires and Transistors with Silicon Nanowire-Channels
Journal of the Vacuum Society of Japan, 2009 Si nanowires (SiNWs) were synthesized by gold (Au)-catalyzed chemical vapor deposition (CVD). To control the morphology of SiNWs, the growth parameters were systematically changed and they were studied by transmission and scanning electron microscopes and Raman spectroscopy.

Silicon Nanowire Band Gap Modification [PDF]
Nano Letters, 2006 Band gap modification for small-diameter (1 nm) silicon nanowires resulting from the use of different species for surface termination is investigated by density functional theory calculations. Because of quantum confinement, small-diameter wires exhibit a direct band gap that increases as the wire diameter narrows, irrespective of surface termination ...
