Abstract

To date, many efforts have been made to build bioenergy devices with geometry at the nanometer level, which provide new tools for bioelectrochemical studies. The use of individual 1D structure as electrodes for electrochemistry has opened a differentiated route toward electrochemical biomolecule studies. Silicon nanowires (SiNWs), as one dimensional structure, play more and more important role in nanoelectronics and optical devices with its unique attractive property. Moreover, with surface engineering treatment, the electrochemical properties of SiNWs at the Fermi level can be tuned with the interesting change from metallic to a nonmetallic character of the transport. Herein the surface engineering of SiNWs with enhancement of optical property addresses. Results show that due to the effect of surface engineering, the structure of SiNWs changes with higher efficient and stable photoluminescence without any luminescence decay, which definitely approve the significantly compelling effect of surface engineering of SiNWs.
