The Silicon Nanowire @Silver Tetracyanoquinodimethane hybrid structure: synthesis and characterizations.

A facial bottom-up method for synthesis Silicon Nanowire@Silver Tetracyanoquinodimeth hybrid nanostructure was developed. The silicon nanowires (SiNWs) array was synthesized by etching silicon wafer using hydrofluoride (HF). The silver nitride was added and reduced into silver nanoparticles (Ag NPs) which can be found on the top of SiNWs. Then the silicon wafer was heated with Tetracyanoquinodimethane (TCNQ) in the bottle. The TCNQ molecular vaporized would react with silver on the surface of NPs and form the needle like anabranches on the top of SiNWs. the morphology of material can be adjusted by changing the reaction parameters, the morphology the SiNWs@AgTCNQ hybrid nanostructure were characterized by scanning electrical microscopy(SEM), Energy-dispersive Xray spectroscopy (EDS), Fourier transform infrared spectroscopy (FT IR), et al. Due to the good field emission property of SiNWs and AgTCNQ. This hybrid nanostructure is the promising candidate to achieve excellent performance on field emission..
