My research involves rational synthesis of 1D nanomaterials (nanowires, nanotubes and nanorods) driven by screw-dislocation mechanism. Unlike the prevailing catalyst-driven growth of nanowires, which are often conducted under high vacuum and temperature that inevitably increases the cost of the synthesis, only two conditions are required to promote dislocation-driven growth: the presence of dislocation sources and low precursor supersaturation. We are aiming at generalizing the dislocation-driven NW growth to a variety of different materials and fabricating more complex nanostructure such axial NW heterostructures using this mechanism. The continuous flow reactor will be adopted to provide constant low supersaturation profiles for all the synthesis, promoting the dislocation-driven growth. The as-synthesized NWs will be examined carefully under the electron microscope to confirm the presence of dislocations and the resulting lattice twist. I also study other commonly observed crystal defects such as stacking faults to investigate how they associate with the dislocation-driven growth. Since no catalyst is involved in the dislocation-driven mechanism, the synthesis can be easily conducted in low temperature aqueous solutions and could eventually become a low cost, scalable and more versatile approach towards 1D nanomaterials synthesis.
